The K-14 Gunsight
I can't tell you how many questions I get related to the K-14 gunsight, so I was really excited when this new manual was donated this week! The K-14 gunsight was used on the P-51 (and other aircraft) and is described in the manual listed below as a precision gyroscopic gun sight that is designed to automatically compute the lead angle required for the firing of 50 caliber fixed guns from a fighter plane, in order to score hits on a target.

We also have another document that describes how to use the K-14 gunsight, which you can find here:
