I recently bought a Postwar 345 Culvert Unloader, car and barrels and it is missing the roof, counterweight, and ramp to match the 342 Loader. The motor works and everything else appears good (tested it with a temporary weight). I have seen several Manual versions of the 345 (Some are referred to as a 346 while others are referred as a 345) at not much more than buying just these parts from the parts vendors. Are the roof, counterweight, and ramp the same for these two versions? There may be some other parts I could keep as spares or as part of my layout junkyard.
Thanks for your help.
