There was one like that in excellent condition listed on GB starting at $999 with no reserve. No mention of box/paperwork. It didn't sell. Looks like a nice gun.
Basically, as a shooter, what any similar 5-inch M29 from that era would sell for in your area. It's not a Performance Center gun, nor is it pinned and recessed. The only thing special about it is the unfluted cylinder, which is kinda cool but not everyone's cup of tea. Having the box and papers adds at least $100 and makes it a candidate for anyone who collects M29 variations.
I bought it a couple of years ago with correct grips, box & docs for $875, and I was happy to get it for that price. I figured it was a $1000 package, but it all depends on who wants to buy it.
The "Classic" guns are similar, but have interchangeable front sights, whereas the "Hill Country" guns have pinned front sights.
Very nice Aktinman love those grips , my gun has the pinned in sight also. I have the original black ramp sight had to put a f/o on it to see it my old eyes aren't what they used to be lol.
