NO
No published sn data.
1968
Lorcin
It was made by Lorcin, and Lorcin is no longer in business.
There is no fixed or standard length. There are serial numbers of different lengths for different purposes.
Look on the butt.
Lorcin manufactured them. They are now out of business.
Depending on who made it, they may or not be published. And, depending on when it was made, they may or not exist. Serial numbers were not required on long arms in the US until 1969.
Serial numbers were not required on long arms sold in the US prior to 1968 so very few companies bothered to serialize their .22's. For some reason, they usually did assign serial numbers to larger caliber rifles.
There is a white sticker on the underside of my Acer Aspire 5570 that looks like this: MFG.DATE..... long bar code... S/N: a long code with numbers and letters (THIS is the serial number).... SNID: a long code of numbers (this is NOT the serial number) I will repeat, the S/N code IS the serial number...not the SNID.
