Ok I don't know whether this qualifies as "machinery", so if not please feel free to move it to the correct sub forum.

 

Does anyone know how to properly and easily identify, differentiate between a Starrett, Brown & Sharpe, Miller Falls old try square heads.  Old being 25+ years. The rules are easy--they are marked, but I can't find any makers marks on the head(s).

I've noticed that on some heads the sides are knurled--for lack of a better description, and some are just smooth.

 

Why do I care?   I'd like to keep the unit with the associated parts.

 

I Gauging marks their heads but I'm lost with the older heads.

No problem. Didn't know either asked a millennial customer.

As long as they keep them to 4 letters. Those multi, multi lettered sexual orientation acronyms have me buffaloed. But then, it took me a while to figure out what CO meant. I did know you had to salute them, though.

For Starrett all the heads will have Starrett and Co marked on the edge. I have some over 60 years old and all are marked. oops just thought all of mine are adjustable square. Is it adjustable (two piece) or try square (one piece ) you are talking about?

 

Not quite what you asked but just found this . Look at beginning about page 400.

I'm actually talking about "combo" squares. The 90-45 head, the center finding head, and the protractor.

I always thought that the 45-90 head was called a try square, Guess I was/am wrong.

Ok lets see if I can get the pics in.

 

These heads appear to be Starrett. The protractor has LSS Co on the edge. The finish appears to be the same Japanning (sp) finish.

Interesting though the protractor head does not accept a Starrett rule but will take a Brown & Sharpe rule. The Starrett rule is too thick.

Part 2

 

these 3 heads take a Brown & Sharpe rule. All have the same finish. Possible B&S?? 

Part 3

 

All have a "bumpy" finish.   The white is chalk to try to bring out the bumps. All take Brown & Sharpe rule.

The "bumpy" finish " is Starrett. I have one just like it. Starrett makes many types of rules and squares and the fit is not universal . some of the rules I have seem to be thinner although I have not tried to measure that.
