I need 3-508, 3-509 and 3-521 if anyone has them. Also ran across a reference to " AERONCA Drawing List 4237" which is purportedly a list by Drwg # and title of all AERONCA drawings. would love to be able to find that too, although my personal needs are relative only to Post War Chiefs. If you can help with any of these, it will be much appreciated. Please don't bother with references to Todd and the museum. Thanks-
Dale
