Interesting lot.
The trammel is a pretty common pattern, but useful for use with a stick and nail, like Bill said.
(I do keep my Starretts clamped to a short rectangle stick, so they don't get separated.)
The spoke wrench is pretty common, especially a small sized Dudly. There are 1/2 a dozen others on ebay right now. It seems nobody knows what to charge for them. From 5 bucks to 125 for the exact same tool. I got mine in the neighborhood of 5.
The hand level is kind of modern but fun anyway. I wonder if there are people collecting these yet? Pretty gizmotic appliances if you ask me. And enough people made them that you could build a collection, cheap.
and what in the world were the deep throat thickness gauges for?
I have one for guitar and similar work, but mine is twice as deep and probably weighs 1/2 as much. These are massive heavy. Really interesting.
Oh, that engraved presentation Dudly is just,,,,,,,,,,,,,,,,,gaaaaaak!! Choking on drool.
