As a new member , I have been going back thru old posts and came across one listing model 41 serial numbers according to Jim Supica's book. The listing starts at 5 digits for 1958 and yet I have a four digit serial number gun from 1958. I think the post was typo error; and Supica's book is not that detailed for serial numbers in the semi-auto guns. Anybody out there know of a good source, apart from a Jenks letter.
