This photo really got me this time.  I did suspect it was a replica of a battleship, because it had cage masts, triple turrets, and a single funnel (Armored cruisers, which also had cage masts, lacked the triple turrets and had multiple funnels.), but it looked too late and was too different to be the Recruit, and I do not recall seeing a replica of a Pennsylvania or New Mexico class before (The replica could not have fitted Tennessee or later classes.).

 There are enough references to warships getting plates welded over some of their portholes once the fit has hit the shan or is about to, to see that designers give even combat ships lots of portholes (Makes ventiliation and air circulation easier, especially if the ship is going to be operating in hot weather climes.).

C.T.

First conclusion: it's not a battleship. Three triple turrets, but they aren't heavy guns. Could be 5-inch or 8-inch.

Second conclusion: WWI-era, or possibly even earlier. No one put portholes like that on a WWII-era warship.

Third conclusion: it's too big to be a destroyer, so it has to be a cruiser.

But I have no guesses about whose it is, or what it is.

A strange thought occurs to me: what if the turrents are dummies? Could it be a passenger liner trying to bluff the U-boats?
