Ref. No. 960. RNZAF SKYHAWK INSTRUMENT PANEL. This panel was initially installed in a US Navy aircraft that saw action in Vietnam. The aircraft was then sold to the Royal Australian Navy (RAN) before being purchased by the RNZAF (the RAN purchased a total of 20 Skyhawks for use on the HMAS Melbourne, but ten were lost to accident and the remaining ten were sold to the RNZAF). As such, this panel (initially from an F-Model aircraft) has therefore been owned by three air forces and was used in combat in South-East Asia.  At present, instruments are being progressively added so that the panel represents a pre-Kahu upgrade version as used by the RNZAF. 
Ref. No. 800. RNZAF MCDONNELL DOUGLAS A-4 SKYHAWK CANNON BARREL AND MUZZLE BREAK.  Barrel  has mark “PAV 195” stamped on it.  Muzzle break measures 153mm long and 50mm in diameter.  Made of stainless steel (?) and stamped with number “28”, as well as inspection mark “U 197”. Has minor dents and has been used.  Probably from a crashed aircraft.  A muzzle break is an attachment on the end of the gun barrel that has ports (or holes in the sides, top and bottom) in order to deflect the propellant gasses behind the bullet out to the side or top of the rifle.  This deflection of gasses stabilises the barrel of the gun.
Ref. No. 946. SKYHAWK ARRESTOR HOOK.Colour matches late scheme used on RNZAF Skyhawks.  Length is 2000 mm and weight is 11 kg

Ref. No. 1022. DOUGLAS A-4 SKYHAWK CONTROL GRIP.  On top is the word “Mason”. Top left switch is the missle guidance switch as fitted to early model aircraft. Central switch is for elevator trim (nose up and nose down) and aileron trim, which is marked LWD (left wing down) and RWD (right wing down) on either side. Right switch is for autopilot.  Bomb switch is maked “B” and is in thumb position. Gun switch on front. On base is number “22411A” and on side is number “4064-938”. A total of 17 wires are attached.

Ref. No. 1073. A-4 GRIP.  On top is the word “Mason”. Top left switch is for nose-wheel steering as fitted to later models of A-4 . Central switch is for elevator trim (nose up and nose down) and aileron trim, which is marked LWD (left wing down) and RWD (right wing down) on either side. Right switch is for autopilot.  Bomb switch is maked “B” and is in thumb position. Gun switch on front. On bottom is number “708-5101”, on side is number “SN1574 8748” and on base  is "DAC 7821711-1"

Ref. No. 1003. A-4 SKYHAWK GUNSIGHT.  Removed from Bu. No. 148610, which flew with VMA-133 Dragons (Tail number “ME” and side number “13”). This aircraft was an AFD-2N, which was later redesignated A-4C.  This aircraft was produced in a batch of 178 aircraft with Bu. Nos. 148435 to 148612. Formerly on exhibit at the Navy-Marine Corps and Coast Guard Museum, it was acquired from NAS by Encinal High School, Alameda, CA in 1984. It was towed to the school, restored and repainted by student volunteers before being placed on display.
Ref. No. 1044. A-4 SKYHAWK MASTER CONTROL PANEL. From an Israeli aircraft, probably an A-4H.  An interesting feature of this panel, and proof of its Israeli heritage, is the control knob marked “Walleye”. The Walleye was known as a TVGB (Television Guided Bomb). This was a US Navy development in cooperation with Hughes Aircraft and Martin Marietta Corporation. They began entering service in 1967 during the Vietnam war.  Israel purchased 204 Walleye II GW Mk 4 Mod 4 2,000-lb TVGBs. This bomb had a 1,000-lb high explosive warhead, based on the Mk 84 2,000-lb bomb. USAF designation was GBU-15.  The panel also has a knob for “Shrike” missiles. This type of missile was used extensively in the Vietnam war to knock out radar stations – the missile homing in on the radiation emitted by the enemy radar. During the Middle-Eastern war in 1973, 490 Shrikes were supplied to Israel with seeker heads pretuned at 2965-2990 MHz and 3025-3050 MHz, the bandwidths employed by the Fanson A and B radars guiding SA-2 Guideline and SA-3 Goa surface-to-air missiles supplied by the Soviets to Egypt.

Only the first eight A4D-5s built were so designated, as the tri-service redesignation system came into effect before deliveries began in January 1963, and the "Dash Five" became the A-4E. Compared with previous models, the A-4E featured a lengthened nose, five wing pylons, more powerful engine, an avionics hump and cranked fuel probe.

RSSK-8A-1 SURVIVAL CONTAINER.  This is part of the ejection seat system and contains, oxygen bottle, ELT (emergency locator transmitter), medical equipment (bandages, suncreen, insect replement, etc), survival items (compass, water container, razor blade, energy sweets, etc).
