@Keystoned Ed posted:As previously commented, the model in the photos is not a Weaver or NJCB BP20 model in that it has a cast metal nose and cab, while those imports had fabricated sheet brass ones. The model in the photo has a nose that is shorter and not as tapered as the prototype. There were significant differences in length between the noses on Baldwin freight and passenger sharks, and as a result the taper angles were different. The model was possibly built using a Locomotive Workshop freight shark nose/cab casting.
I agree with PRRJIM, the trucks, gear boxes, and open frame motor appear to be a Central Locomotive Works components. In its day it was a remarkable model.
A cast metal nose and cab screams LWS.
