I have the chance to buy a model 99 in 300. i know little about these guns and neither does my friend, who is selling it (he inherited the gun).
I want to offer a fair value for the gun and need some help.
based on the serial number, the gun is from 1941
has a checkered pistol grip and forearm, marble rear sight
the gun was used on a ranch, so it shows definite signs of wear but no major scars.

any help would be appreciated
