Would agree and say in its current state bore condition is the main driver of the price. you could also get a good deal more selling individual parts. check out what good quality parts on https://www.granpasgunparts.com are going for.
Although, because full stocks new or old are hard to come by, not to many people restoring these. There are wood shops that will make a new full krag stock and handgaurd for $400 or so. I dunno how much you paid for it, but in todays market with a little sweat equity restoring it to original configuration could pay off....you already have most all the parts.
I'm in the middle of such a restoration myself in another thread, started with just a barreled action. but I won't be selling.
