Yes,, these smaller Pilot kits are really not in demand like the larger Royal kit might still be..

I'd search "completed listings" on ebay also

I'd expect you'd get at least $100 to $150 for the pilot kits and Royal zero and the other 25-30 size kits,, Posting them on Ebay probably your best bet

I'd need more info on the b-17

I'd ask $200 for the Goldberg Chipmunk,, that will sell fast

Good luck,, and Sorry for your loss
