Pete, SAL had quite a few Mikes. I've modeled their USRA Q-1 (492) and Q-3 (411):
I think the NYC would be found under the 2-8-2 H5 series, but I can't determine which ones as they had a load of the "H" class. They could have come from one of their subsidiaries, not sure.
Here's what the fireman's side of the Williams Mike looks like:
As you can see, the one I just bought isn't close to the color of this one. I was going to paint it black and keep it as a Southern engine, but then I'd have to get a Southern caboose to go with it so I decided to try and keep it in the ACL/SAL family of engines I already have.
I want to see if the fireman's side of the Williams is close to the NYC, or if anyone has photos of the AB&C engines that would be fine too!
