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,
