On 19 March 1967 this aircraft had been towed to Southend by road from Stanmore, Middlesex, where it had been standing in a garden for some years. In the course of the BHAM converting it back to its military scheme as NP339, Aviation Traders (Engineering) Ltd. allowed the use of part of their hangar for the paint work, during which it was daubed with the false AT(E)L Class B marking G-41-4.
