Earl,
If you've lurked around here (or done some decent searches) you know there are thought to be only 25 or so of these guns that left the factory in normal channels.
Think of any Smith & Wesson, Colt, etc. model handgun of which under 50 legitimate copies were made & sold...
Soooo... Is the gun for sale or do you THINK possibly it will go UP in value as the years go by (presuming of course it stays in unfired, factory-original Mint Condition) ??? Hmmm? Sell it today and you'll have a perfectly good reason to kick yourself in the azz for the next twenty years!
I don't own any museum pieces. My guns get used. But if I stumbled into a 5-shot 480Ruger Alaskan in ANIB condition, I' believe I'd letter it and handle not very much.
