I have a nice picture of the USS Concord, rated as a gunboat
The USS Concord took part in the Battle of Manilla Bay in 1898. This is a photograph dating from 1891. The Concord was actually a small cruiser, with a displacement of 1710 tons and with 6-4in guns.

The gunboat Concord, really a small cruiser
I have a photograph of the gunboat Concord taken in 1891. In this picture, the Concord resembles the small cruiser that she really was. The Concord had a displacement of 1,710 tons and dimensions of 230ft x 36ft x 14ft. The armament consisted of 6-6in BLR and ten smaller guns. The crew was established at 14 officers and 181 men. In the photograph that I have, the Concord had recently been completed. The speed was on the low side at 16.8 knots, but that was all that could be achieved with 3,404 HP. The Concord took part in the attack on the Spanish fleet at Manilla Bay in 1898. The Concord had one funnel and three masts, with a gaff rig.

The American wooden torpedo boat Stiletto
The Stiletto was a fast wooden launch, built by Herreschoff Mfg. Co. at Bristol, Rhode Island in 1885. The little Stiletto displaced 31 tons and had dimensions of 88ft-6in x 11ft x 3ft. The engine provided 359 HP, enough to reach a nominal 18.22 knots. The Stiletto had a raised forecastle (just about 3ft) and a single funnel. The wheel was situated on the deck at the end of the forecastle. The forecastle was narrow and did not go the full width. There is a good photograph from 1886 that I will post, when I can take a photograph.

The Russian cruiser Novik
The German-built cruiser Novik was the best cruiser that the Russians had, although admittedly, it was just a scout cruiser. Much better photographs are now available than we used to have, since Russia opened up to the west. The best all-around cruiser the Russians had might have been the French-built Bayan. The Novik was a novelty, in that while launched in 1900, the Novik was rated at 25 knots with reciprocating engines. Jane's said that 26 knots had been reached on trials. I tried the ship in Springsharp and was able to make the design work, if I used very lightweight machinery:

French central battery ships
I am still amazed that the French kept their central battery ironclad battleships from the 1870's in service into the 20th Century. They were rebuilt, at least. The Reboutable is listed in Jane's with a date of 1876. They were ships with top speeds, as designed, as low as 13 knots. With a single screw, iron armour no more than 14 thick on a complete belt, I have trouble seeing how they provided any useful service besides training. They did provide a number for strength comparison lists, but by 1903, their value was extremely low. They also had the problem of having a narrow belt, almost submerged, with about a 60mm deck on top of that. They had high, unprotected sides.

Jane's Naval Gun Notation
Fred Jane had devised a notation to describe the power of guns, which was intended partly for use in his wargame and partly for use by naval officers and analysts for comparing ship capabilities. The notation used in 1903 used capital letters, sometimes with numbers appended:
Jane then rated armour with similar letters, so that you could tell what gun could penetrate what armour at close range. The numbers were altered at longer ranges.
Notation Gun Length Muzzle Velocity Projectile Weight
A5 16.25in 30 2,087 ft/sec 1,800 lbs
A3 13.5in 30 2,016 ft/sec 1,250 lbs
A4 12in 40 2,750 ft/sec 850 lbs
A3 12in 35 2,367 ft/sec 850 lbs
B 10in 30 2,040 ft/sec 500 lbs
BA 9.2in 45 2,550 ft/sec 380 lbs
B 9.2in 40 2,347 ft/sec 380 lbs

More about the Mersey class of 1885
The Mersey class consisted of the Mersey, Severn, Thames, and Forth. They were protected cruisers of nominally 4,050 tons. They were 300ft (between perpendiculars) x 46ft x 19-1/2ft. They had a 3in steel deck. They were originally armed with 2-8in/30 BLR, 10-6in/26 BLR, 3-6pdr QF, and 8-3pdr QF guns. They also had 14in torpedo tubes. The Severn had one submerged bow tube and two above water. The Mersey had two submerged and two above water tubes. The Forth and Thames each had two above water tubes. They ships originally made 17 knots, but by 1903 were only good for 15 knots. They normally carried 500 tons of coal but could carry as much as 900 tons. The engines were horizontal compound.

One question is what would be the best wargame rules for the period from 1870 to 1905?
Perhaps lumping 1870 together with 1905 is inappropriate, but some fairly old ships were still in service, at least up to 1904, when they were finally hulked or scrapped. I would like to find a copy of Fred Jane's naval wargame, as I would like to see what he was doing. I suspect that we could figure out a way to improve on his system for shooting. He was a successful wargame designer in that he sold quite a few sets of his game and some important people played it.

The battleship Royal Oak, rebuilt in 1902
I have this old photograph of the battleship Royal Oak, one of the old Royal Sovereign class ships that was rebuilt in 1902. The photograph shows the Royal Oak still in Victorian livery. The photograph was apparently taken in either 1902 or 1903.

Fred Jane's sketch of the Orlando class
I have a copy of Fred Jane's silhouette sketch of the Orlando class belted cruisers. The sketch was made sometime between 1899 and 1903. The cruiser Narcissus belonged to this class.

Fred Jane's silhouette sketches
The very old Jane's All The World's Fighting Ships, prior to 1905, Jane had these little silhouette ink sketches of ships. They show the steam pipes and he points out differences between ships in the same class. I am not sure about the rights situation, but Jane's ship diagrams that show the armouring scheme are all over the internet, so I will try showing one of his little silhouettes. As an artist, I think that they are little gems. If you have not seen a Jane's from 1899 to 1904, you probably have not seen one of these silhouettes. I have thought that you could make wargame pieces that looked like this.

An old photograph of the battleship Vengeance
The battleship Vengeance was one of the faster battleships that sacrificed some armour for higher speed (battlecruiser-like). This is a photograph dating from prior to 1904 showing the Vengeance in Victorian livery. Other ships in the class included the Ocean, Canopus, Glory, and others.

An old photo of the cruiser Hawke in Victorian livery
This is another old photograph, from some date prior to 1904. This is a photo of the British cruiser Hawke. A distinctive feature is the flush deck and relatively low freeboard.

I have this picture of the belted cruiser Narcissus, painted white for the tropics
This photograph of the belted cruiser Narcissus dates from prior to 1904. The Narcissus is shown painted white for the tropics. In cooler climes the ships were painted in the usual Victorian livery, but that was unsuitable for the tropics.

A Cornwall class cruiser in Victorian livery
I have usually seen the Cornwall class light armoured cruisers painted gray and with funnel markings. This ship is shown prior to 1904 in typical Victorian livery. The ships were rated at higher speeds, but the original trial speeds were only 21 or 22 knots, probably due to propellor problems. They had 4in side armour and carried 14-6in guns.

The cruiser Marathon (1888)
This is a photograph of the British 3rd Class Protected Cruiser Marathon. The Marathon was armed with 6-6in/25 guns. These were originally BL guns, not QF. The Marathon was nominally a 2,950 ton ship with a 2in protective deck. This photograph dates sometime prior to 1904. The ship much must be painted for tropical service.
There is also this nice photograph of a sister ship, the Magicienne.

British ships painted gray in 1903
I have some Symonds photographs that show definitively that the British navy was painting ships gray in 1903, prior to Admiral Fisher becoming First Sea Lord. The pictures that I have show the 1st Class Cruiser Spartiate, the fast armoured cruiser Good Hope, the battleship Mars with funnel stripes, and the battleship Russell. In the set, there is also a fascinating photograph of the old cruiser Mersey, launched in 1885. That ship is still painted up in the Victorian livery.

The battleship USS Louisiana
I have a good photograph of the pre-dreadnought battleship USS Louisiana. The photograph was taken in 1911, after the Louisiana was modernized with cage masts and painted gray:
I tried a Springsharp design, as well, to see how well Springsharp handled this sort of ship. I found that Springsharp assumed machinery that was too heavy. I had to lighten the machinery to obtain a satisfactory design (Springhsharp reports don't work well with this blog template):

A rare photograph of the battleship Texas, taken in 1899
This rare photograph of the battleship USS Texas was taken in about 1899. The Texas had fought at the Battle of Santiago in 1898. The Texas was at least a second class ship, if not a third class battleship. The Texas carried two 12in guns in single turrets mounted in echelon. There were also 6-6in BLR guns (not QF). On trials, the Texas averaged 17.8 knots.

A photograph a 1903 battleship-cruiser
At Dreadnought Cruisers, I recently posted my design for a 1903 battleship-cruiser that I thought was along the lines of what William Hovgaard had proposed. This is a 24 knot ship with 8-12in/45 and 12-6in QF guns. The armour basis is 10in. This is a photograph of one of the ships:
