last week, a very mint 3" 66 with original box & cleaning kit sold for $750 @
Guns International, Antique Guns, Collectible Firearms, Used Guns For Sale Online
they did not give the dash #, but it was either a 2 or a 3. i called for more info, and quite possibly purchase, but it was already spoken for, and the lady on the phone knew nothing about the gun.
this letter states roughly how many 3" 66s were made. i wish it would have been more specific about how many -3s, and -4s, had been produced.
