does it have something to the effect of "made in the 200th year of liberty" printed on the barrel??
pics would help. ruger makes a LOT of varients. i cant find any 41mags made in 76.
from your info it sounds like a blackhawk single in 41 magnum value in my blue book goes from 400-700$ depending on condition add 50-100 for liberty barrel. 700 is new in box with all packing materials pieces and parts manuals etc. 400 is 85%
