Only thing I know is there is a note that says the following are checked and correct 0001 of an inch. There is one small circular thing with a roughly 10 in handle that screws into it and 6 various-sized bars that attach somehow.

My guess would be a device to measure the inside diameter of a cylinder. Would be used with an outside micometer.

I agree, but you would not need the outside mike, the rods are machined and checked for certain lengths, the micromere is the handle
that reads the same as a micrometer, but you add the rods lengths to the reading.

They look like reamers.
When drilling (or boring) a hole to a tight tolerance you drill it undersized, then you ream it to the exact size.
Machinist tools, I would say.

not sure which set but these

Hello, I agree with turnnut & bill. The photo is blurry, so I am guessing what we see is rust, and or , discoloration on the rods, that gives them the look of being ridged. . Regards, Lou

Yep. Inside micrometer. I somehow own two sets, neither of which I've ever used; but I'm ready, if ever called on to, say, measure the inside bore of a steam cylinder on a locomotive.
