Martin JRM Mars seat....this replaces my prior post with correct information


Recommended Posts

This post replaces my post on the Martin JRM Mars pilots seat with known information. As you may know I went  down a rabbit hole looking to identify a seat I came across. That seat is in another post. First  off these are photos of the JRM.

What little that can be found on the pilots seat of the JRM are of the proto type. The pilots seat of the proto type is different than the production model as  seen in photos and drawings.

In the other known photos are of the Coulson JRM's cockpit. The original seats were replaced decades ago by the seats seen in it now. An expert on Warren McArthur seats personally inspected the Coulson birds and confirmed this.

The Smithsonian Air and Space museum sent me documents they had on the JRM. Note the last document identifies the seat  as a Mod. 262 made by the Warren McArthur Company.

The following is the only flight deck photo I could find of a production JRM. Note this  seat is different from the prototype JRM and is not like some of the documents. After that you will see the actual photo and files on the Mod. 262 seat from the Warren McArthur archives. On the last document on the far left you will see the number 262. This document is from 1944 and shows the seats were being refined during production and tested.  Warren McArthur seats have a look to them. The US Navy used these seats in many of their crewed aircraft during WW2. They kind of look the same at first glance, but they are in fact different configurations using the same basic parts.
