Ref. No. 1143. 1138. ENGINE DATA PLATE V-1710-F3R. Air Corps or Bureau Mode - V-1710-39 AC 42-35123, Mfrs No. 10808, Contract No. DAW535AC67, Engine Spec No. 123-E, Accepted 4 21 42. This data plate was fitted to a P-40E aircraft used by the RNZAF and could have flown in Tonga. This plate is from one of four types of Allison engines fitted to four different models of P-40 flown by the RNZAF during WWII and was collected by an airframe mechanic, William Albert Leitch, in the 1940s who served in the RNZAF as a LAC. He collected a wide variety of plates from different engines fitted to RNZAF aircraft. These included P-40 Kittyhawk, C-47 Dakota, F4U Corsair, Lockheed Hudson, PBY Catalina, SBD Dauntless, de Havilland Mosquito, Short Singapore and a Blackburn Baffin. Leitch died in 1991.

Ref. No. 1139. ENGINE DATA PLATE V-1710-F4R. Air Corps or Bureau Mode - V-1710-73 AC 42-85308, Mfrs No. 17575, Contract No. DAW535AC1098, Engine Spec No. 159-A, Accepted [blank].  This data plate was fitted to a P-40K aircraft used by the RNZAF and almost certainly flew in combat against Japanese aircraft. Research by Mike Nicholls shows that the engine this data plate was fitted to was installed in NZ3056 which crashed at Ohakea on 19 May 1945.

This data plate was fitted to a P-40M aircraft used by the RNZAF and almost certainly flew in combat against Japanese aircraft. Research by Mike Nicholls shows that the engine this data plate was fitted to was installed in NZ3147 which was sold to a Mr Larsen after WWII for scrap.

P-40E RING SIGHT, PART NUMBER 87-69-613-     Being made of steel, this P-40 ring sight shows heavy rust damage due to its many years of exposure in the Papua, New Guinea elements.  Total length is 9-5/8 inches and the diameter of the outer ring is 3-3/16 inches.   This ring sight, coupled with a bead sight post in front of it served as a back-up in case of failure (ie, light bulb burnout) of the illuminated gunsight that was installed in the cockpit directly over the instrument panel.   The ring and bead sights were located on the engine cowling just ahead of the windshield and to the right of centerline of the fuselage, so the pilot had to lean slightly to his right in order to line up with his target.  Basic, but affective as a back-up.  The blood chit design in the background was originally used by Claire Chennault's FLYING TIGERS to persuade the Chinese people to help downed pilots get back to their bases.  Also used by the Hump pilots who flew supplies to Chennault.   This is made of a silk-like material, probably rayon, and measures 8 X 10".   Although this chit bears  Generalissimo Chang Kai Shek's "chop" (seal) this bloodchit was made in Washington D.C. as indicated by the "W" before the serial number, "4617".  D Collier

P-40N CANOPIES. The centre canopy (which slides to the rear) on the P-40N is distinctive with its rearward sloping bottom part of the transparency and is a useful way of identifying the full-size P-40N model. All three pieces as shown measure eight feet long .  D Collier
CURTISS P-40 TRIM WHEELS.  These was also used on the Curtiss P-36 "Mohawk", which is why the number "75" is molded in the control wheels. The Mohawk  was the 75 series, and the P-40 was the 87 series.  These trim controls was used throughout the entire P-40 production line.  Its assembly part number is, 87-64-006, which are made up of many parts, each having their own individual 87 part numbers. D Collier.
P-40 GUNSIGHT ASSEMBLY - Although there were gunsight variations from country to country, this was the most-common gunsight configuration for the P-40 aircraft, and its part number assembled is, 87-69-964.  Each seperate piece has its own "87" part number.   Pictured here is the gunsight mounting yoke, 87-69-952, and reflector head assembly, 87-69-961, which are mounted on a Lend-Lease 108B illuminated gunsight body.   This 108B gunsight was made in New York City by  STAR MACHINE MFRS. INC. for the British-Commonwealth under the U.S. Lend-Lease program.  It is the British version of the U.S. Army Air Corps' N-3A gunsight with the single-pin electrode.  (The N-3B had the double-pin electrodes). This gunsight assembly is missing the set of rails that mounted from the top-front of the mounting yoke to the front of the reflector casting, where a green sunscreen could travel over these rails to cover the clear reflector glass, and was actuated by a manual lever that mounted to the hole shown in the side of the mounting yoke.   D Collier.
A-1 BOMBING HEAD.   In addition to the standard Curtiss stationary gunsight reflector head, (P/N 87-69-939) used for aiming fixed wing guns only, some P-40's also used the variable-angled-reflector known as the A-1 bombing head on their N-3B gunsights. (pictured)   Like the N-3A and N-3B gunsight bodies, the A-1 reflector was generic and used on other planes as well.  It had an adjusting wheel on the left side of the head that was used for adjusting the angle of the reflector glass  to compensate for the trajectory of a falling bomb.  The zero on the calibrated adjusting wheel was set for fixed wing guns, and the other increments were set for various bombs at various altitudes.   This reflector is "live" and shows how it would look from the pilot's perspective if switched on - the interior bulb and lens focusing reticle and ring as shown. What is missing here is the Curtiss rubber crash pad, (P/N 87-694-1016) which clamped to the gunsight body directly below the bombing head.  D Collier.

*Ref. No. 933. P-40 GRIMES C-1 FLUORESCENT COCKPIT LIGHT.  Original box marked “One unit Army Type C-1 Fluorescent Cockpit Light Part No. B-1873 Cont. No. N288s-23515 Stock No. R17-L-7454 Grimes Mfg. Co. , Urbana, Oh.” Marked on adjustable neck is “Faries Mfg” and on end disc is “Grimes Mfg Co Urbana, Ohio OH10 B-1873 Air Corps Spec. 94-32254 A Type C-1 Pat Appd For”.
Ref. No. 947.  RNZAF ROUNDEL FROM P-40.  Includes some stringers, the double skinned radio bay access door, and aircraft fuselage skin from top access hatch for hydraulic reserve tank to below roundel - about 80% of the fuselage side..
Ref. No. 521. P-40 KITTYHAWK MAGNETO SWITCH. A.C.Type A-8. Rear reads “Briggs & Stratton Corp, Milwaukee, Wis. USA B-41 3I-I97” Has connections for Right, Left, Ground and Battery. Shown clearly in photo on page 69 of Chris Rudge's book Air-to-Air - The Story Behind the Air-to-Air Combat Claims of the RNZAF.
Ref. No. 846. P-40 CONTROL COLUMN AND GRIP. Claimed to be from a “Mk I P-40”, which would mean an aircraft built for the RAF.  The grip is standard for several WWII fighters and can be seen on P-40s and aircraft like Harvards.  The stick is straight and chromed.  This does not match those fitted to P-40s, Harvards (see below), or P-51 that I have seen in book photographs.  The chrome shaft does have an alloy plug fitted to the base however marked “CT1”, which, given the way it is fitted, indicates the shaft is genuine and not a replica.
Ref. No. 390. KITTYHAWK/MUSTANG TYPE N-3A GUNSIGHT. Circa 1940. Label reads “Gun Sight Type N-3A  Spec. No. 93-24859 Contract No. W535-ac-109 No. W535-ac-20225 Mfg. by Service Tool & Engr. Co. Dayton, Ohio.” Gunsight does not have angular glass head but otherwise appears complete. Tag attached to sight reads “RNZAF Form No.429. Serviceable. Section 108B. Description Sights MG. Remarks No longer required. Date 20/10/58.” This date coincides with the year that the RNZAF scrapped its Mustangs. This gunsight is shown on page 22 of “Mustang at War” by Roger Freeman plus in Pilots Notes. Further information in British Aircraft Armament, Volume 2, RAF Guns and Gunsights from 1914 to the Present Day [1994], by R.W. Clarke, indicates that the N-3A (mentioned on pg 183) was also used on P-38 Lightning, Martin and Emerson turrets, and the P-47C & D.
Ref. No. 633. KITTYHAWK REFLECTOR MOUNT P-40 KITTYHAWK. Circa 1940. Numbers on side “87 69 939 C L844”.  Attaches to top of N-3A gunsight as shown above and reflector glass fits into 45 degree slope shown at right.
