Vehicle blueprints

[dougiebarder]

Hello!
I'm looking for a bit of advice. I met a chap today who has a big pile of ex army blueprints for a lot of postwar (just) vehicles ( series 1 landrover, austin champ, ford, dennis, bedford and who know's what else?) But he doesn't know what to charge for them (and I don't know what to offer).
So the question is what would the eminent members of the forum suggest was a ball park price? (or even better, has anything similar been sold recently?
Cheers
Matt.
