I just acquired this apparently rare bird. It is marked Model P 72 and has no import markings that I can find. Its a Sako sporter in .22 LR, 22" barrel, single stack detachable magazine, all steel bottom metal, high luster blue and stock finish. As best I can tell, it pre-dates the Garcia era. Anybody know anything about this gun and is the magazine interchangeable with the later Sako Model 78 or the Finnfire?

THANKS!
