I suspect there is more thats not been discovered yet,, an aquaintance purchased the nose spinner off an Me109, the part was in Russia and after agreement on price the spinner arrived in the USA, next his contact in Russia offered him a complete instrument panel from the aircraft, this time it didnt show and he was unable to contact the seller anymore, this was not a scam as it was COD, so the buyer was out no funds, he suspects the seller found a "109" and was stripping it for resale and got caught. I have seen the spinner personally and believe it is off a JG 52 aircraft as the spinner decoration matches this one;
