I will do some research into the actual missions they performed,maybe i can find some interesting ones for the game.
Two types i found schematics for,Type 227 was build the most.You can also see the different aft designs,the type 127 has aft dive planes too.
But they look like 2 totally different designs with some simularities,i'm kinda puzzled about it and intrigued!The model is a mixed one..
