Tailfins have made some skin squares from left over metal from making previous products from an Olympic Airways Boeing 747.
The Olympic Airways Boeing 747-200 MSN 21684 rolled out and started its life with Singapore Airlines 9V-SQI way back in 1979. It flew for several years with the national carrier before moving to Olympic Airways in 1985.
Skin squares come with a Tailfins certificate. Tailfins are made from genuine aircraft and can be traced back from there first flight to being scrapped.
