I really appreciate old pre-lock Smiths and despite cutting back these days I'm always looking for them. However, I'm amazed at how much the older Smith revolvers (and older Colts and Rugers for that matter) have largely disappeared from dealer's shelves.
Having said that, I've found Arizona Firearms at their Tempe and Gilbert locations as well as AJI in Apache Junction do seem to occasionally have some nice Smith revolvers. But they do seem to be few and far between these days.
