This is basically the same engine, Pete. Just lettered different. And I have no idea what version it is, either. Seems there were different versions.
I tried originally to fit batteries in the side tanks, but the sides of the tanks bulged out.
If you look at the 2nd picture, you can see brackets inside the boiler that are squared off. They hold the motor block. And I had thought about cutting them off, but decided to put it all in the cab. The picture Don sent me the inside of the boiler didn’t have those brackets and the motor block itself looked a lot smaller. He suggested the same thing. He also managed to mount a speaker inside the boiler.
It’s all enclosed in the cab so it should be hidden.
There wouldn’t be any room for an on/off switch under the tanks since I plan to put the weights back in. See the first picture.
It’s a small engine and almost as much a PITA to do as the Shay I have.
