The Winchester 325 was cataloged as the .22 MAG version of the 320, both of them being detachable magazine fed bolt action rifles that were cataloged circa 1972, but I don't know what year they first appeared or the year that they last appeared in Winchester catalogs.

The Winchester 145 was cataloged as the .22 MAG version of the 141, both of them being tubular magazine fed bolt action rifles that were cataloged in the mid/late 1960s, but I don't know what year they first appeared or the year that they last appeared in Winchester catalogs.

I've never seen a Winchester 141 either.

I'm a fan of the Model 320, it is among my ten most favorite bolt action .22 LR rifles and since I am also a fan of the .22 MAG cartridge, I currently have 24 of them, and would like to find a Model 325 if they actually exist.
