I need a brass spring for my Newton #2 combination square, which appears to be a copy of the Starrett design. It's about 1/4" i.d., and (was) slightly longer. It broke. I sent Starrett an email for part PT01086 SPRING, #11 .257X.308X.563. Hopefully I am not unjustly prejudiced, but I have little expectation of receiving a response, since I am a little guy, not a machine shop. Thanks! M
