I've just been given an old DeWalt 7740 radial arm saw . It's mostly in good working order, however, it is missing the mitre scale gauge at the top rear (a.k.a. the protractor) - it also doesn't latch in at 0 or 45 degrees but I'm expecting a little TLC will remedy that. Would anyone just happen to have a gauge lying around? I'm pretty sure it could take one from a similar model (740, 7730, etc.). I know it's a long shot, almost interstellar, but worth asking the question.

Cheers,
