I'm going to add that bore condition isn't that universally important. If someone is a collector more than a shooter, or isn't buying the gun to be a shooter, then bore condition can take a very, very back seat to other considerations. I've got a couple of guns with pretty dire bores that I have specifically because they fill a hard to find niche in my collection, and the bore situation wasn't really a consideration when I was getting them.
On the other hand, my shooters? Especially my modern shooters? Bore condition is more important than just about anything else, up to and including things like finish condition and originality of parts.
That said, a bolt m/m is more likely to be valued as a shooter than a collector's piece. THAT said, it also depends on the collector. The crowd around here tends to have much higher expectations and generally be fairly advanced in their collecting.
From where I sit $800 is very low. That's RC territory these days, and this gun is a damned sight nicer than an RC. I'd personally price it closer to $1200.
edit: I think people here, who tend to have multiple all-matching rifles that they bought for sub-$1000 decades ago, often times loose sight now how many beginning collectors there are out there and what prices have done in the last 20 years. There are a lot of people out there who would be happy for worn, honest, bolt m/m at $1000-1200, doubly so one with an uncommon code that is harder to get.
