... come to think of it, I think there was a drawing of it in one of the "Random Japanese Warship Details" books from Tamiya... not sure where I left them though...
I'm thinking a misprint here...A fairly basic refit of the KBL Class gunboats. I've decided to keep the underwater torpedoes as they might be handy.
