Gerry,

Nice wood. My guesstimate would go up particularly if it is well matched on the other side.

I didn't remember a KHP on the one I returned but it appears that the stock oval is engraved and ends with a P. Looks like the owner's initials were engraved on the bottom plate. Some would see this as having a negative effect on value and some would not. Grouse do not read stock ovals or bottom plates. Enjoy the gun.
