Sorry I know this is small fry but within Europe, anyone know how much I should list these for?

(or ideally I'd trade them for the red Brumowski DIII and/or the silver Nieuport 17/23

Sopwith Camel (Stackard)
Fokker DR1 (von Richtofen, red)
Fokker EIII (Buddeke)
Hanriot HD1 (Scaroni)
Bristol F2B (Headlam)
Nieuport 28 (Rickenbacker)
Albatross D.Va (Jacobs)

and one of the new Wings of Glory playing mats

thanks!
