Starrett edge finder?

[Batmanacw]

This is the first Starrett 827B I've ever seen like this......



It had a bad spring in it from a smaller edge finder. Someone rigged it with a fishing spinner but the end isn't supposed to spin. Probably a non-machinist.

I had a spring that worked. It seems to work on both diameters.

The end is 0.2" as usual. The larger diameter is 0.620. I thought that was odd. Easy math though. The reach on it is pretty long so that is helpful.

I'd love to find the original spring someday. $10 at the flea market.

I never have either. I'm starting to think it's just in a Starrett box.
