Base pin has always had me a bit confused too. Plus I've been told the trigger isn't right - too wide? I got this from a member (Cecil ) here years ago and there were some questions back then. For a while I thought it might be a re-blue but I'm convinced it isn't. It is however a nice OM Super I call a shooter, even though I've never shot her. My first 44 OM.
