Hi all. I have the chance to purchase a John Rigby Mauser in 338 Winchester Magnum. It has the look and feel of a high quality rifle, as it should, but I am at a bit of a loss as to what range of values would be fair to both a buyer and a seller. I would like to make an offer that would treat us both fairly. It is a normal 98 action with thumb cut. No scope mount and not drilled and tapped for mounts either. This is good since the safety and bolt handle would interfere with a scope! Since the 338 Win didn’t exist until the late 50’s this seems odd to me and would certainly reduce the rifles value, or at least the number of people interested in it. Any guidance from those with more experience than I have on express rifles? I’m not certain if an unscoped 338 is very useful.
