These assemblies may have been taken apart, reconditioned or otherwise restored and reassembled. A so called 'original' aircraft may include many replacement parts. For my purposes a rebuilt aircraft is one which substantial portions of the original aircraft were replaced. Some of the aircraft are nearly complete rebuilds starting with little more than a dataplate while others consist of portions scrounged from several airframes.
