Is there a published table of A.H. Fox shotgun manufacture dates by serial number? I have McIntosh's book, but it doesn't contain one. Elliott's Lefever book does have one for that company.

I am specifically interested in birthdate of a Sterlingworth/Savage (12) in the 137,000 range; I think 1930's?

My apologies if this is an old topic that has already been discussed...
