... So who was Shaws? ...
As a guess, "Shaws" was a stockmaker from California. The 1971
Gun Digest in the "Directory of the Arms Trade" within the category "Stocks (Commercial and Custom" lists the following:
Shaw's, 1655 S. Euclid Ave., Anaheim, Calif. 92802I did not check issues before or after 1971.
