Hi Jim

From what I can tell, mind you I'm not wearing my glasses, but it appears to be a razor made by "Sterling." Don't mean to be a smarta$$. Honestly, I would use some MAAS on it, attach some scales, and give it a few laps on a hone, then shave test it. Only you can be the judge on whether you have found a sleeper of a great shaver or just an awesome letter opener. I too found an unkown razor at an antique shop, couldn't find much info on it, but it turned out to be a great and smooth shaver.
