I truly appreciate everyone's reply. A local guy has a nib Weatherby mk xxii. A Nikko magazine fed version. It's beautiful with the original Weatherby scope. I'm really on the fence. Problem is he won't just sell it outright. He's an as$&*#@ that way.
Tell him to sell it outright, for an honest price, or go to hell. And then walk away. I'm telling you now, that there is not much difference in the value of that K-31, and that Weatherby. One is N.I.B. and the other would be if you had a box to put it in. If he laughs at you direct him to the Simpson's link that Dave posted. High conditioned K-31 are going for four figures. I'm talking 95-96% guns. Yours looks like a 99% gun, easily. Are you sure that it has ever, even been fired?
I mean, what kind of a deal does this guy want? If he expects you to give him that K-31, and a lot of cash on top of that then he is a highway robber. And if you take a deal like that you will regret it, because ten years from now that K-31 will have appreciated faster than that Weatherby. And here is why: The market for a N.I.B Weatherby Mk 22 is pretty much limited to Weatherby lovers and collectors. The gun is just too expensive. The average guy looking for a .22 auto will just buy something cheaper, like a 10-22. The market for high conditioned milsurps is serviced by a much larger pool of potential buyers. Military collectors drool and dream at night about finding pristine, near new or actually new pieces. Some collectors specialize in rifles, or pistols, or WWII guns, or a certain countries guns or...you get the idea. But all of them will usually jump at the chance to grab a high conditioned, near new specimen regardless of who made it.
Here's another thing to consider: What class of guns seems to have appreciated the fastest in the last few years? That's right, milsurps. Remember those $99 Nagants? Or the $99 SKSs? The $79 Nagant revolvers? Average K-31s used to be $129. This was just a few years ago. Look at the prices now! And a pristine near new (or actually new) K-31 will appreciate faster than average. High conditioned guns always do.
If you don't keep that gun, at least make sure you get a good deal for it.
