Model 52 B Magazine question-|Winchester .22 Rim Fire|Forum|Winchester Collector

Hi there!

I’m new to this page, so forgive me if this has been asked in the past (I didn’t see it), and maybe this isn’t the right spot to ask…

I acquired a Model 52B , heavy barrel, a few months ago, circa 1950.  It had a single shot adapter when I got it, and a nice Lyman STS 10x on it.  Had it at the range today for the first time, and truly amazed by it.  Looking into finding original 5rnd magazines, however, thought I saw somewhere (can’t find it now), that the normal 52 magazines won’t work in a 52B. 

Do 52B’s use a proprietary magazine?

thanks, 

SW
