It has emerged that there is some confusion over the Manufacturer's Serial Number of this aircraft. The MSN was originally reported to be 7191 (Aviation Letter 389/55), however it was recently pointed out that published sources (e.g. Putnam) quote the MSN 7192 for BuNo145921. In an attempt to clarify this once and for all, the writer sought the advice of the aircraft's owner who has kindly supplied an image of the data plate which states that the MSN is 7203 and the BuNo 145921. It has been established from U.S. Government sales lists that when BuNo 145921 was sold ex Davis Monthan, it was without a data plate. Evidently, the original purchaser has found it necessary to manufacture a replacement data plate to facilitate registering the aircraft in the United States. The current owner of the aircraft confirms that the data plate depicted above is the one which was attached to the aeroplane when he purchased it and he has no knowledge of any necessity to produce a replacement data plate. That the plate depicted is not the original data plate is evidenced by the following:

(a) It describes the aircraft as an SP-2H, a designation which did not come into effect until 1962.
(b) On the basis of published serial listings, the MSN 7203 does not match the Bu No 145921.
(c) The Lockheed Model should be 726-45-17 (not 726-45-14) and it should appear in the Manufacturer's Model box, not the Plate Number box.

  On the available evidence, there can now be little doubt that the correct MSN for BuNo 145921 is 7192. Why the original purchaser chose an incorrect MSN cannot be determined, but clearly this is of academic interest only, as there is no doubt that the aeroplane is ex BuNo 145921 and it is this number which appears as the "serial number" of VH-NEP on the Australian Register.
27AUG22 The aircraft was inspected at Cunderdin. Although dusty and with faded paint, it is reported that the owner works on the aeroplane almost every weekend and several offers to purchase have been declined.
