I went back and looked over the guns again yesterday, this time with another friend of mine and also a friend of the family. He is actually my barber and Jim's (the deceased husband) barber. He is a long-time gun collector/shooter/accumulator. He and I went through the guns, using a Blue Book and our combined knowledge/experience to arrive at prices we thought the guns would bring. He is into military weapons and I'm not, but we usually came within $50 independently when assigning values. He did assign a much higher value to a really ratty looking old M1 Carbine than I would have. He wound up buying that gun, along with four more, including a rusty 94 Winchester, a very rusty Stevens 311 in .410, an old Ithaca 49 that had mud in the barrel, an M1 Garand with mis-matched serial numbers, and a bunch of loose ammo.
I brought another rifle home with me to advertise locally on a couple of forums. It is a very nice looking FN Mauser Sporter in .308. I did some research and it looks like FN exported these guns and barreled actions to the US from the late 40s through the middle 60s. It has a Weaver K4 scope on it, and it really looks like a quality piece. I might list it in the For Sale section here for f/f sale in Georgia.
