    From the Australian Archives, this is the manual for gunsights. This sight was used on the p-40 Kittyhawk and others.

    Hope this link works! :rolleyes:

    Very useful manual, looks like "the teacher" took over half way through and did some marking :D

    3/10 needs to improve layout :(

    Does any one have any photos of the sight in situ in a kittyhawk/P 40.

    This one just makes me confused 'cus it doesn't look like a N2/N3

    Do you think it looks more like this

    http://www.warbirdsite.com/P-40gunsight3.jpg

    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.

    Hi Dan,

    The unusual looking gunsight in the P40N is a standard Air ministry gunsight (same as spitfire). A lot of RAAF aircraft appear to have had them installed. I have one of the mounts - it just bolts on in place of the standard late Curtiss gunsight yoke 87-69-952. I am not sure why this was done other than perhaps because the AM sight was a superior unit to the N3 reflector sight.

    Then there is the earlier Curtiss mount as well.....

    Regards Mike
