I bought these three items a while ago at a local flea market for $5. I had been looking for a small center head with a small rule. Well, I found two and then added an older Crescent wrench. The wrench was pretty clean, but the two center heads were not.
The bigger center head with the longer rule baffles me a little. Is it a Starrett? The rule is marked but I only see an 1880 patent date on it. I know that that can precede the date when it was made by decades. The knurled nut has grooves that run at an angle and the rule is as thick as a 12 inch Starrett rule. Anyway, it is straight and perfectly usable, although I had to clean up the rule to see anything.
The smaller Lufkin - I think - was only covered in paint and cleaned up well.
If anyone knows more about the Starrett (?) center head, please let me know.
