My LGS here in San Antonio has some interesting vintage models of a very nice variety. And naturally, they have a whole line of modern day plastics, after all, they need to stay in business somehow.
They usually have some very nice S&Ws, in fact, I just purchased a late model 1917 commercial from them, now one of my prize possessions.
They have a Model 48-4 in there that I have looked at from time to time. Interestingly, they have it somewhat hidden, as opposed to that excellent 1917 which they had prominently displayed when you enter the store. I've been looking for a nice something in .22 magnum (no autos, thank you) for some time.
They are asking $799 for this 48-4, which sounds like a pretty good price to me, don't know if they have the box for it or not. Attached is a picture of it from their website. It's pinned, so I believe that means it was made between '77-'82 or thereabouts. I've handled it, seems to be as good as it looks in this photo.
I'd be interested to here some thoughts, I got some pretty darned good advice on that 1917 I purchased recently. In general, this LGS always has pretty good deals, just not the greatest customer service, which I've discovered to be the norm these days.
