A buddy of mine passed away a few months ago and his wife has put me in charge of selling off his guns. She found an old revolver in the bottom of a shoe box the other day and handed it over to me. It is a High Standard Sentinel MkII in .357 w/ a 6"bbl and fixed sights. Other than the fact that it was made by Dan Wesson in the mid-'70's, and marketed by HS, I can find out very little about it's value or collectibility. It is in reasonably good condition, a couple of small rust spots, and the general lack of polish and lubrication that one might expect in a handgun that hasn't been handled in 20 or so years...nothing that a little TLC can't fix. Any thoughts?
