Well, as all RC k98k's are usually looked upon as parts rifles to the collector's crowd, they still arguably have a place in history, even as rearsenaled by the Russians.
If this rifle does indeed, have 'capture papers', it has an even higher value, as it was actually used in combat, unlike a large percentage of the RC 98's that have come into the US for the last decade or so.
As RC's are gradually coming up in value (around $400 currently, give or take), one such as the rifle in question should be , in my opinion, kept aside, and if a shooter is desired, there are PLENTY of other k98's around that would fill the bill easily.
One has to remember that the k98's selling now for $1000 and up (quickly, depending on year/code) were at one time running about $20 in hardware store barrels.
My thoughts on it.
Your rifle, though, do as you will.
