Old Dial Guage information required

Would anyone happen to know if this is a standard dial guage or is it related to an aero engine?

From the items it was with it must be early 40’s – and in need of some TLC 😮

Any information would be appreciated.

Regards

Looks standard and pretty much the same set is still available. Quite likely to have been used in aero though, are there any engraved property markings that might give a clue?

Cannot see it very well, but it looks a lot like the dial guages we use to check the (plus an minus) runout (at the prop hub flange) of fixed hub crankshafts, usually either after a prop strike, or when purchasing a used engine. Maximum allowable runout is usually around .005 and varies a bit depending on make & Model of aero engine, along with the various arms, extensions, and clamps needed to affix the base to a stable section, in order to get the dial onto the face or side of the hub or crankshaft
