@prrjim posted:The underside with the open axle gear probably dates this to the 1940s-50s at best. However the level and quality of the detail that appears in the photos compares well with newer models. I don't think it is a Brass Import. I think it might be scratch built either by one of the custom builders of that era, or an individual for personal use.
It appears to be a nice model...
I probably shouldn't even comment, as I am a complete novice (   but if you look at the lower portion of the cylinder, it appears that there are some "flattened filed" areas, so I would also guess scratch-built.
In any case, a very "nice model" indeed. You should be pleased.
