I have a Replica Railways B! which altho' 18 years old has not had much wear. However the wheels and linkage are worn out. I need either new ones or advice on where to get the parts. The loco is driven from the rear wheels and the wheels turn independantly causing the motion to lock up. The connecting pins are very worn and are loose and fly off. I did have the engine running with the wheels araldited onto the plastic spacers but not for long as the pins drop out. I do not want to scrap it but it may be the only answer. Anyone out there with some bits?
