After all this recent talk about MS 1910's I pulled my old one out of the safe for a fondle this arvo.

For the first time I noticed a number other than the serial number and was wondering if any of you guys might know what it means.

The number is FF5971 and is stamped on the top of the knox form just in front of the chamber.

The serial number is in the usual spot and consists of 4 numbers only.

Any help would be appreciated.

Cheers.
