Then there's these: the ticket on the front is just some trinket, as it says, a "souvenir", interesting now simply for
the fact they used the old Ford Tri-Motor airplane. In the back, though, is a listing of what appears to be occupations,
or types of training, with rough times in months or years on the right. I think that is a rough "resume" of sorts, a listing
of the various training and schooling Grandpa got over the years. Perhaps it was a quick note he jotted down
as he was filling out a resume for one of the later jobs, who knows?

Still, it's fascinating to see things like "tool room machinist", "gear design" and "Brown & Sharpe cam design" in there.

I had no idea- none- that he was any sort of machinist. I'd always thought he was a draftsman. One of the other things I got
was a packet of engineering drawings, one of which includes what's labelled a Brown & Sharpe cam. Such cams are, or
rather were, used to run mechancial production machines called "screw machines", typically called that because one
of the more common uses of them was to produce screws. Once set, they can run for literally years, but as all
the motions are controlled by precision cams, the design of those cams is something of a "black art".
