Skorzeny (Otto?),
I've got one. Actually, I guess technically my ex-wife has it. A one of a kind Detonics. It has a full size Government model frame with a Commander length slide (all steel), single stack magazine and a factory Seecamp DA conversion. It's a duplicate of the old ODI Viking, but it is marked Detonics. You won't find it in any book anywhere as I understand Detonics bought the parts in the white, no markings, with the intention of purchasing the tooling and selling them under their own name. But Detonics folded and some of their engineers took the parts, serialed and stamped them and assembled an unknown number of complete guns.
Now, since I think you wanted a full size, ODI did make a number of full sized guns, though most were Commander length.
Do I win the prize??

Personal weapons are what raised mankind out of the mud, and the rifle is the queen of personal weapons. The possession of a good rifle, as well as the skill to use it well, truly makes a man the monarch of all he surveys.
