B-17E 41-2595 Restoration Update: July 29, 2023

B-17E 41-2595 Restoration Update: July 29, 2023

The restoration crew at Marengo, Illinois, working to restore B-17E 41-2595 (otherwise known as Desert Rat) continues to make steady, if slow, progress on the challenging effort. For those not familiar, this rare B-17E was recovered from a remote farm in Maine way back in 1985 by current owner and team leader Mike Kellner. It was in terrible shape, having been subjected to an unsuccessful but damaging attempt to scrap the bomber. Now, jump forward through four decades and the airplane is slowly coming back together in airworthy condition in a purpose-built building in rural Illinois.

As can be seen, the fuselage is structurally complete. Much of the smaller parts and assemblies that still need to be added are underway by trade, fabrication, or outright purchase. It is detail oriented.

The restoration started in earnest around 1993 or so, and the first and most ambitious challenge was to structurally rebuild the fuselage after it was cut into pieces earlier by those seeking to turn it into scrap. Also, there was a large, non-standard fuselage cargo door added when this particular B-17E was modified by the AAF to become the sole XC-108A, and that cargo door had to be removed and the structure replaced. This structural work required manufacturing many new and specialized longerons and formers to replace those cut, and jigging the fuselage so things would line up properly. All that work on the fuselage structure was completed several years ago.

For those who have watched the effort in recent years, progress is not readily apparent but, in fact, much work has actually been accomplished. In particular, the complex airframe structure around the ball turret is completed, as is most of the restoration of the camera bay located forward of the ball turret and aft of the bomb bay. The work effort by Kellner and his all-volunteer crew is now focused on the important carry-through structure in the bomb-bay which consists of, among other parts, the wing attach points. New steel tubes had to be extruded to exact Boeing specifications and carefully installed in place of the old, unairworthy tubes. This is exacting work because the tubes hold the terminal fittings that will mate to the B-17 inner wing sections. Being off a eighth of an inch just won’t fly later when trying to attach the wings. As the photos show, new terminal fittings on the fuselage side are being installed. Most of the components to complete the bomb bay section are now available, and the parts are being fitted and riveted back into position. After the carry through structure is completed, the bomb bay catwalk is built and ready for installation. After that, it will be bomb racks and bomb bay doors plus the actuating mechanisms…the list, it turns out, is pretty much endless.

The all-important carry-through structure that holds the wing attach fittings and girdles the bomb-bay is the last major structure of the fuselage that awaits completion. Most of the custom-made parts are now on hand so it is a matter of carefully assembling the structure back into the fuselage.
The bomb-bay catwalk assembly that becomes part of the carry-through structure is complete and ready to go back into the fuselage when the time comes, hopefully in the near future.
The right forward fuselage side wing attach fittings are in position and will soon be permanently riveted back into the assembly.
As can be seen, the right side forward lower wing attach fitting is a newly created part, as is much of the important structural components in the bomb-bay carry-through assembly.

After the fuselage structure is completed, the cockpit area will need to be reinstalled. At some point in the future, the electrical and other systems will need to be recreated and installed as per the original Boeing specifications.

A beautiful instrument panel complete with all the instruments is in storage and ready to be installed at the appropriate time. Components for the operable top turret are being assembled offsite. The top turret dome rests in place on the fuselage.

The wings recovered from the field in Maine are eventually going back into this airplane. They have received some work, but attention has primarily been on the fuselage over the past few years. One of the wing inner sections has been stripped out for cleaning and evaluation. The two outer wing panels have had the skin removed in jigs and will be reskinned as time allows. There are four engines present, but all four will need overhauls, as will the propellers.

Seen here is the left wing stored vertically, with the completed tail gunner compartment stored in front. This wing has been opened up and partially disassembled for inspection to evaluate what will be needed to bring it back to airworthy condition. As is to be expected, particular focus is directed toward the wing spars.

As can be seen, this restoration effort remains a monumental task. Mike Kellner and his small volunteer crew are devoted and spend many days each week working on the small pieces that gradually become the big pieces. As in any such restoration project, finances and labor are the challenges. If you live in the area around Marengo, Illinois, and that includes the greater Chicago and Rockford areas, and have some talent, experience, or just enthusiasm, Mike would like to talk to you. Perhaps contact Mike via email. Many parts have to be created from drawings or pattern pieces, so someone with that skill set would be ideal.

New Desert Rat Pages at aerovintage.com

One thing I’ve just done is updated all the old dedicated Desert Rat pages on my website. Though I am not connected with the Desert Rat team, I think it is an effort that should be supported by the warbird community. I would encourage you to take a look at these pages as they offer a history of the airplane and the restoration project.

And if you are able to provide any donations, big or small…every bit helps…then please step up. If you go to the above pages, you will see a donation tab at the bottom. Consider donating the equivalent of two cups of Starbucks coffee (that would be $10) per month as a regular, automatic donation to help create a funding stream to keep this project going. Well worth the now-absent two cups of coffee. If you are already heavily caffeinated, perhaps consider the equivalent of four cups of coffee…every donation does make a difference.

Of particular historical interest is this fuselage skin that was removed from the right side aft fuselage. It had to be replaced due to its condition, but it is of greater historical value as an example of the paint and markings worn by this and many other B-17s. Remnants of the red disc can be seen inside the star, as well as the added white wings and red outline of the insignia. Peculiarly, the visible white star seems to extend into the red border…either applied incorrectly or we are seeing several versions of the star as applied. An interesting artifact worthy of any serious museum.
Another interesting insignia on the removed skin panels is this emblem of The Air Transport Command. This is dated from the time that 41-2595 was operating as the sole XC-108A cargo transport as part of a service test. Mike Kellner has been told by some experts with the current Air Mobility Command that this is the only known application of this insignia that survives.
