PZ474 History

Built at Hatfield in early 1945, PZ474 was delivered to No. 19 MU on the 19th of April, then to No. 80 OTU on the 5th of May, No. 132 OTU at East Fortune on 13th June and subsequently into long-term storage with No. 151 MU on 18th February 1946

PZ474 was sold to the New Zealand Government on the 23rd January 1948. Following an order for around 90 Mosquitoes by the New Zealand Government (the first of which left on 11th December 1946, but it was nearly 18 months before the order was completed), PZ474 was taken out of mothballs and given a thorough overhaul. It was then flown to No. 1 Ferry Unit at Pershore, Worcestershire to be made ready for its long delivery flight. PZ474 was amongst the last six Mosquitoes to be transferred.

Flown out of the UK by an RAF pilot on the 4th March 1948, PZ474 arrived in New Zealand on the 15th April and was allocated a new RNZAF serial, NZ2384, and allocated to 75 Squadron.

It is unknown how much, if any, flying the aircraft did with the squadron, but it was evenutally put into outside storage at Taieri.

On the 16th of October 1952, PZ474/NZ2384 was amongst 6 Mosquitoes inspected by Arthur Kaplan and Bob Bean, American representatives of Aircraft Sales Inc. of California. The 6 Mosquitoes were subsequently purchased from the Government Stores Board by Aircraft Suplies (NZ) of Palmerston North in July 1953 destined for export. In September they were placed on the civil register and allocated the registrations ZK-BCT to ZK-BCY (PZ474 being allocacted ZK-BCV) and overhauled in preparation for their ferry flights.

Following the departure of PZ474/ZK-BCV for America in February 1955, the New Zealand Government prevented the export of the remaining Mosquitoes, believing that they were destined for overseas military use.

Allocated the US civil registration N9909F, the aircraft was owned by the Insurance Finance Corporation of Studio City, California. Its subsequent use is unclear, however it appears to have been used for intelligence gathering operations by the CIA in South America.

Ending up at Whiteman Air Park, San Fernando, California, PZ474 was cancelled from the civil register in December 1970. Abandonded, the aircraft started to deteriorate and at some point the fuselage was cut behind the main wing, leaving the aircraft in a very sorry state.

Jim Merizan heard about PZ474 in 1970 and moved it to his home in Placentia, California, then to Yorba Linda. In the 1980's, Jim Merizan apparently traded ownership of PZ474 to the Swedish Air Force Museum.

The reason that the remains of the aicraft are where, and in the state, they are is unknown.
