I eagerly downloaded this, only to discover it's more of a top-level listing. For instance, one of the most often replaced items is the gear that engages the motor worm, and they just list the complete motor.
The gears for tinplate are in the Part List document Service sent out in the ASC update.
OOPS! Just saw the Marty posted it. G
I know, but they should have been in that Tinplate Parts book, they're probably one of the most common parts that fail.
That is your opinion. So let MW know. I think the parts that would be tech installed are left off. What I saw was all the folks that wanted detail parts to restore there original Pre War, or Complete motor assemblies to also use for restorations.
Changing out the gears is more elaborate and near complete disassembly. So that would mostly be done by an ASC. OR for the expert modelers they would know how to ask for the part. G
