Maybe a mock-up? Too bad there's no pictures looking inside.

Yeah, it might be a mock up. Agreed, I do not see props. The rudder is welded right to the body of the submarine. No evidence of actual planes. The hand rail around the sail looks odd to me. Probably a hollow shell :hmmm:

If you look the ends of the railing are open and look a little off, but they might have just been unfinished. But some other details just appear somewhat shoddy and unlike what you might expect to see on a working submarine...

I think it is a Bulgarian submarine that might have plied the waters of the Black Sea. :03:

I thought that too, Soviet Malyutka-class from WWII. But its too short, the sail is in the wrong spot and it appears to only have 2 tubes (it could have four but where would the engines go?)

Unless you are talking about some other boat, the only Bulgarian subs I've found were one in WWI, this, whiskeys and romeos.

looks like a "Sea-wolf-fodder" class

I'm sure those rails are just added on to keep visitors from falling off, and not the sea-going set-up.

Or there's always that :smug:
