Hello. I have two model Cathay Pacific planes in fairly poor condition, Transfers are worn and chipped and some engines are missing from one of them. One is a Lockheed TriStar L-1011VR-HHX and the other a Boeing 747-267B VR-HKG They are both in the lettuce leaf livery, probably 1980s. They appear to be made of wood or resin and are quite solid and heavy. If I could have any info on these such as the composition and manufacturer and if they are if any value to a collector I would be very grateful. Thank you.
