This was built as an Piper L-18C for the USAF and was given the US military serial number of 51-15628. Its Piper construction number was 18-1628. Under the MDAP scheme it was supplied to the French Army (ALAT) and received the French military serial of 181628 (the same as its Piper c/n).
By early 1970 it had been withdrawn and appeared on gthe Belgian civil register as OO-SPL with the Aero Para Club at Spa. On 24-06-1982 it turned up on the UK civil register as G-BKEZ to Anthony Nicholas Gouvenot-Gardiner of Hitchin (I suspect via Cliff Lovel who is a well known restorer of - especially DH aircraft). In OCtober of 1984 it passed on to Goeff Harfield of Newbury and then to David Marwick, down Farnborough way.
