Yes otto. The boiler is slid too far back in this picture. I want paying attention when I took it. I'll get a better picture up later.
The tender trucks are from a class j auxiliary water tender.

Looking at the drawing, I am seeing some problems now.
The thing that worries me is that the cab is supposed to move forward, but the rest of the boiler should not.
Assuming you haven't glued the cab to the boiler yet, the cab needs to move forward.
The front edge of the cab is supposed to be just forward of the driver #4 axle. That's obviously not hard to fix.
The reason I say the rest of the boiler should not move forward is that the back edge of the boiler tapered section
is supposed to be right where you have it, over the center of driver #2.
But that tapered section is supposed to extend all the way to the center of driver #1. It looks to me like the tapered section is a little too short. On the drawing, it looks like it's about the same length as the two sections in front of it. If it were the correct length, the stack would end up over the cylinders.
