In the course of compiling a photographic archive of the Ruhlen photos of Corregidor Pre-War, I came across three photos of a peculiar gunsight. The photographs were given the name "Morgan Gun Sight", and despite attempts to locate any explanation of anything about them, I have come up with nothing. Does anyone know more about them, how they work etc? Here's a link to the particular pages : corregidor.org/archive/ruhlen/mills/html/mills_08_04.htmIf you find a photo you'd like to write a caption for, msg me. A link to the series, which is almost completed, is at: corregidor.org/archive/ruhlen/ruhlen_00.htmIt is the best pre-war photographic series I have seen of Corregidor yet. Thanks go to Shawn Welch, who is our source for the series.

Batteryboy’s “shelf of doom” coughs up something on the Morgan Gun sight.
The Morgan Machinegun Gunsight was developed specifically for the 59th CA by Major Maurice Morgan for the 1936 target practice. It’s designed to give a large number of hits on an aerial target flying on a limited variety of courses. Although results in 1936 were satisfactory the improvements on the sights in 1937 led the creator to believe that it can be adapted as a standard for the Coast Artillery AA.
The rear sight takes care of the superelevation element while the front sight handles the target lead in an inclined plane. In other terms, the rear sight takes care of the ballistic data while the front site takes care of the geometrical data necessitated by the movement of the target. The separation of both sights gives it an advantage as the geometric data is expressed in a single item – i.e. the measurement in the direction of the target’s apparent movement.
The device was also tested by the 60th , 91st and 92nd CA regiments.

Mr. battery boy, good explanation. What are the other types of gunsights that were used? I saw some of the old machineguns with different types of sights?
One last, what is the "shelf of doom"?

Coast Artillery used several sights for their MGs. Let me dig up a few when I get home.
As for the shelf of doom, that will explained outside of this topic.
