Stopped by a shop I haven't been in for a month or so. In the consignment case I spotted a very nice 4" 13, turned out to be a -1. Turned out to be a "D" serial number from probably 1977, 4" p&r (obviously), pc magnas (didn't ask to see if they number), no box but some kind of holster (didn't ask to see), factory spec sheet, easily 95% condition (conservative on my behalf). Priced at $595, I'm not in a spot to buy right now otherwise I would've taken it. It's been there a week and they don't accept offers on consignment guns until they've been on display at least 2 weeks.
If anyone in the Denver area is interested it's at Green Mtn. Guns in Lakewood. I have no connection to this gun, nor do I have any idea who it belongs to. Thought someone around might be interested.
