I recently purchased two new old stock Weaver RS3 locomotives. these appear to be early production models. they have a horizontal mounted Pittman motor with a drop down chain drive that connects to a tank drive to both trucks. As was expected most of the wheel axle gears were cracked as well as the chain sprocket on the motor shaft. I have already replaced these parts using P&D hobby shop as a source and the units are now running. They came with no cab window's which I think was how these early productions model came. I found this source for cab windows online.
I am not familiar with this vendor. any one know of any other sources of cab windows ?
