I picked up a super adjustable antiquing the other day. It is in great shape has the black plastic bottom so 78-86 . I posted a few months back about where the date code is. I got some responses saying inside the blade tray. I could swear there is nothing there aside from maybe a few scratches I can't see a letter or a number. Is it possible it is missing the date code, is it somewhere else....? I can snap a few pics a little later if it will help. Thanks in advance.
