I'd say this is a Viking frame. It's a licensed copy of the Seecamp conversion. When the company went belly up, the leftover parts were sold... I believe to Essex. Quite a few frames were sold off as kits. Quality was suspect from what I remember, but do recall a couple of people that were please with their builds (Note that the original Seecamp conversions are true masterpieces). Looks like the pivoting trigger was removed on this one. I've read that people converted theirs back to single action, as the double action was to heavy. Nice part of the conversion was that the firing system worked the same as a typical 1911. The pivoting trigger cocked the hammer, but the standard trigger released the hammer. Don't know what it would be worth in this shape. The trigger and transfer bar would be near impossible to find. Probably have to have them built. As is, I'd maybe go $300.00.
It might be a Viking, but it sure looks like my old Seecamp. I had one made by Seecamp shortly after they started doing it and the mods to that 1911 frame are identical to it. Mine was a Commander, aluminum, and he had to put a steel feed ramp in because as Rangemaster and firearms training officer at the time, I did a lot of shooting. I always carried it in halfcock condition because trigger pull from that position was much better than with hammer full down. I sold it to my partner when I retired, and he sold it to a gun shop when he retired. Sure wish I had it back!
There was a gun sort of like that circulating the gun shows here a few years ago, except it had the ODI slide, too. Either they had a stripped ODI frame or could not make the rough DA kit parts work that were sold off after the Viking operation folded.
All the "true" Seecamp conversions I've seen had a hook in the front of the trigger guard. Then his initials (LWS) would be stamped on one side of the hook. Pretty sure that was on all of this work, that's why I'd say it is a Viking frame. Out of curiosity does it have a traditional grip safety and mainspring housing? Some of the Seecamps had a one piece unit that did away with the functioning of the grip safety.
Thanks for the information. I ran across this in a local gun/pawn shop and was just wondering what it was. It has a grip safety. but it appeared to have been pinned down. The owner did not know what it was, but he wanted $300.00 for it.
