I appreciate the responses. Specifically I am looking for a book or website that would show the pictures of different period boxes or corresponding dates. I have a 1940's L.C. 16ga and various 1930's 410's, I would like to have some classic Peters Boxes for that time period but am not sure as to the dates the Peters boxes were made buy looking at the box's. I see them on Ebay, Gunbroker, Auction arms but not sure how to date them.... Thanks again
