For info, you can post them here & we can make a stab @ them.
If you are looking to get the most money, that would be over time and your time either on Guns International or Gun Broker. On Gun Broker you could set a minimum considering comps and then drop it a little after a couple cycles should they not sell. I have literally zero idea of fees & cost.
If you just want to dump them, The Attic in the Dakotas probably would pick them up as they have some knowledge and import European arms.
Lock, Stock & Barrel would be another >>Dump<< option, and they actually come to you. You just check their trajectory, meet & sell them.
Actually, I think both The Attic & Lock, Stock & Barrel take consignments......
In the event you can't post them, I will gladly do that for you.
