hole in outer tube to view numbers.

Tread depth gauge?

Why would a pressure gauge have those units and graduations?

I'm not sure what it was for, but it works like an inside micrometer, with 1/32" graduations. It would be useful for measuring the width of wheel rims, up to 5", which is a fairly narrow rim. Probably obsolete by the early 1950's.
