How to sell Herpa planes to original collectors?

Question

Been collecting aircraft models since 1996, 1/500 & 1/400 most models I have are no more in production or from the 1st version. Been trying to sell models as a set for each airline but it seems hard to fine a true collectors. Mostly are just intrested to sell it the next day at higher price.

Answer 1

If you have any information on these resellers, you could google their names and that way, you might be able to see where they are selling it "the next day", and just sell there.
