Yup, Mark, those are the photos that I used for my comparison.

Here is an image of the engineer's side of the Alco 2-6-0 model:

Here is an image of the engineer's side of GBW 2-6-0 #56 (later #256) built by Alco (Schenectady) November 1924:

I think that the new 2-6-0 is based in the GBW 56/256 based on the photo link ...

I compared this to the John Campbell Photos and the drawings in the MR Cyclopedia Vol 1 - Steam Locomotives (drawing 19 page 46)and the model is very similar to the 56/256 before the 1939 rebuilding. 

The engineers side of the model appears to be an exact match to that of the builders photo in the Cyclopedia.  The tender, cab, dome placement, unevenly spaced drivers, valve gear, piston valve cylinders, running board, headlight, bell placement, cab placement, sand pipe, and brake gear appear the match between the model and photo

The only difference that I see is the type and placement of the air pumps on the fireman's side. 

Too much of the details match for it not to be based on the late GBW 2-6-0's.

I am a very happy Green Bay and Western fan and modeler.
