Identify This Tool

[walterwoj]

I picked up this set of Starrett inside micrometers (I think) at a rummage sale last year ($25!!!) and have been trying to identify them.

I believe they are missing the 5-6 inch rod and the .500" sleeve/spacer. I think I can get replacements from Starrett but I have to know what model it is. Any Gurus out there who can tell me the model. I have looked them over and have not found any model markings, just the Starrett branding.

Inside micrometer. I have several. You can make your own replacement for a missing rod. Calibrate with a micrometer or by comparing against a known rod where they overlap.

@walterwoj Edit: I should learn to read more carefully.. I have the Starrett micrometers as well. No idea as to model no. If you can't find the parts from Starrett, you can make your own. The 1/2" extension is simple, just a .500" bushing with an i.d. to fit the shank of the extensions. To extend the raqnge of my limited set, I machined an extension which has a shank to match the diameter of the extensions and drilled to accept the extensions. Mine is 2" long which gave me an additional 2" for the measurement range.

Your inside micrometer is a Starrett #124. Rods should be available.

It looks like the 1/2" long sleeve is missing.

It looks like the 1/2" long sleeve is missing.

The sleeve should be available as well.
