[GreenKeys] Model 19 Gear Set

[Joe Clanin]

Hi Everyone,

I have switched out the gear set that came with one of my Model 19 sets
with a standard 60 wpm set I had around. My question is about the old set.
I am having trouble finding it in any list. The pinion is stamped 74505,
the gear is 74151.

Anyone have any information about these or a document containing them?

Thanks,

Joe
