I cannot find the answer on the Browning site. All the serial numbvers there have SIX digits. My cal. 16 has five numbers too. Serial numbers X58301-X74000 were manufactured in 1952.

10000 or so.
Serial numbers are not exclusive to one gun - hence, there is no way of answering this question, even if you had provided the serial number.

I have one without a SN.
I don't know if all High Standard A-100 rifles (semi-auto, .22LR caliber) had serial numbers. Gun companies didn't have to use serial numbers until 1968, and a lot of inexpensive .22 rifles and shotguns didn't have any serial numbers back then.
