I wonder if anyone can help me identify the manufacturer of this set of 2ROS F3 engines. I bought these about a year ago and I have depleted my backlog to the extent that I now have time to look at them. The F3A is unpowered and it has cab shell detailing inside with control stand and seats for the crew along with the electrical panel etched into the back wall. The F3B is powered with a kind of belt drive that utilizes a toothed timing belt to transfer motion from a clutch/flywheel assembly to the trucks. Motion is provided by a can motor, which I had to replace because the original went bad. Mechanically the drive unit is quite nice with ball bearings throughout. The weak link is the belt and I would like to locate spares even though none are required right this minute. The existing belt shows no wear as of now.
Any help would be appreciated. Thanks for your time.
John
