It is impossible to do with just the serial number.
You have described it; a 22 LR semi-auto
OM was used for 1960 production of the standard Auto-5.
Impossible to answer with any degree of factuality.
A Colt 1908 hammerless .25 with that serial number would be 90 years old. Made in 1920.
Browning.com has sn data under customer service
your colt 25 cal semi-auto was made in 1972.
It would depend on the guns condition as well as caliber being .45 ACP, or .45 Auto Rim.
Please include the model of Winchester semi-auto shotgun you have so that along with the serial number I may give you the correct year of production.
Who made it? What caliber? What kind of action (bolt, pump, semi-auto, over/under)? Serial numbrer?
Need to know caliber, barrel length and whether it is a revolver or semi-auto pistol in order to answer.
