I cleaned it out and will see if that is all it was.Was nothing extra that I saw but after 80 years it might just have needed a little love. Stock fit still seems not a problem for function. I refuse to let anyone convert it from the original design that is why I asked if anyone had a smith who could repair it if needed. My local smith might fix a lot of things well but he is not a trigger man. Funny thing is he does everything else very well but I doubt he has seen two of these single/double Brownings' if that. Several people have PM suggestions for whom to send it to if needed.
