Hiya folks, I'm trying to identify some thin flat stamped metal measuring devices I found in my grandfathers toolbox. There are 29 in all, and the all have the part number prefix MC, as in MC-86, MC-85-162, MC-122, etc. He was a Chrysler mechanic from the late 40's to late 60's, but he seemed to dabble in just about everything. None of them are date stamped, but my best guess would be from the 1950's. I couldn't find any reference to them in the standard catalogs. Any ideas?

They are carburetor gauges. that's probably the right time line.

you can find then in the 1953 catalog page 39 (collectingsnapon.com/catalogs/catalogs.php?loggedin=0&catalogPage=1345)

Yes, those are them, thanks!
