Thats what I told him as well but he was having none of that. He was trying to tell me that even if an Avery stamped destroyer has patent numbers on it that it is still a Pre-Avery.
Well, I mean technically he's not super wrong. If it still has patent numbers that means it could have been molded pre avery, even if it wasn't stamped or sold until after. Granted calling an avery stamped pre avery is kinda ridiculous.
Shoot, I saw an patent # S/DS on ebay with a 2015 tournament stamp on it a week or two ago.
