Hi folks, is this drawing from Convair (Model 63) or from Lockheed (476L/ C-141)?
The picture description at SDASM flickr Archives might be false.

In a manner, it may be a little bit of both. Given the T-Tail is in the foreground of the illustration, I would not be surprised if this is a Convair illustration of the Lockheed C-141 Starlifter.

While Convair's proposal in the the competition to build what would become the C-141 would lose to Lockheed-Georgia's, all was not lost. Convair San Diego was chosen to be a subcontractor on the program, manufacturing the C-141's tail assembly.

Valley News (Van Nuys, California), November 2, 1961, Page 123,
"Another California company today had been approved as a major subcontractor on the giant jet cargo transport being developed by the Lockheed-Georgia Co. at Marietta. Ga. The Convair Division of General Dynamics Corp. at San Diego was approved by the U.S. Air Force to build the tail assembly, a contract totaling several million dollars for the first five aircraft. Received Subcontract Follow-on work and subsequent contracts would extend for several a in this major U.S. airplane program."

There are also photos in the SDASM collection of the C-141's tail being assembled at Convair San Diego. Here's one below:

I think I see why the Convair design wasn't selected. Those rear doors are hideously complex, would be a nightmare to keep working right!

There's a reason why pretty much everyone has settled into a 2-piece rear door, split horizontally (unless you need to carry some very outsized cargo, then you do the C-5C 3-piece doors).
