Hi Martin,

I finally received some definitive information concerning how the expended cases and links in the solid nose 8 gun A-26B Invader were handled. I posted my question on the Yahoo A-26 forum, which you had listed on your web site, and Rick Elwood from the Pacific Coast Air Museum in Santa Rosa, CA responded that "The 8-gun nose collected spent shells and links in a canvas bag in the lower rear part of the nose. They were removed after each flight through a large access door in the bottom aft of the nose."

I asked him if he could send me the pages which covered this in the technical document that he referred to (Maintenance and Erection Manual AN 01-40AJ-2) and I recently received this excellent information.

I scanned the three pages and thought I would send them to you and you could post them in the "Drawings/Illustrations" section of your web site if you wished. I checked with Rick to ensure it was okay with him, and he gave me the green light. I am therefore enclosing the three pages from the Maintenance Manual for your information.

In the e-mail that you sent me on April 14 2008, which contained Don Vogler's comments from a B-26K armament crewmembers, it sounded like the cases and links were not collected in a bag, but rather just piled up in the nose of the aircraft under the guns. I sent Don a subsequent e-mail to try and get some further clarification, but as of yet, I have not heard from him. If I do, I will let you now.

The B-26, designed as a low-level attack bomber was equipped with two remotely controlled gun turrets. The upper turret was mounted on the top of the fuselage above the bomb bay. The lower turret, used exclusively for ground strafing, was mounted on the underside of the aircraft. In addition to the 6 to 8 .50 calibre fixed guns in the nose, there were 6 .50 calibre guns in the wings and rocket rails. The aircraft carried a crew of three, Pilot and Navigator up front side by side and the gunner in a compartment in the rear.

The remote control turrets were operated through a periscope type gun sight. The Gunner occupied a bicycle type seat. A heavy duty four inch lap belt was all that held him in position. As the Gunner sat towards the rear of the aircraft, he was subject to twice the G force of the Pilot and Navigator. Unlike most gunnery systems that were designed as defensive weapons, the Invader systems were designed for offensive action. Special talent was required to operate the gun switches when the aircraft was in a steep turns at high speeds and low altitudes.

The upper turret could be locked to fire forward and was then controlled by the pilot.
