Gil,
Gil,
I have a printed table/list of the year of manufacture marks. This list begins with Year 1945 and Mark I and ends with Year 2001 and Mark BP.

My Beretta SxS is Marked XX which the table tells me it was manufactured in 1964. The mark is on the barrel flat directly under the serial number.

Do you have a mark under your serial number? If so, I will be glad to look it up for you.
