Speaking of odd parts left setting around at the end of a project, while a process engineer at T&C Livonia, I got tasked with walking a bunch of special gear blanks through the hobbing process. It turned out that they were a small part of the GT40 transaxle program.
When the GT40 went to the 427 engine, it was decided to create a transaxle to take the new load of torque the engine would be generating. Simply put, a case was designed to contain both the inside of a toploader and all that goes into a nine-inch differential. The gears themselves were a special batch with improved metallurgy.
We built more of them than were actually needed in the racing activity, and for several years thereafter they set on shelves in a storage area across the aisle, but not far from the door into the QC lab and process section. I used to walk past several times every day, glance up and shake my head at the dreams...
One day I noticed they were gone, and soon thereafter I chanced to be talking to the Plant Executive Engineer, Bruno Z. I asked him where they'd gone to and he told me he'd simply shipped them to H&M. I understand that a lot of stuff ended up there after the racing was only a memory.
Bruno started to walk away at the end of our discussion, and then he turned back and said, "You didn't want one did you? If I'd known I'd haven given it to you."
I don't know what I'd ever have done with it, but at the very least it'd make good garage art. I could have displayed it along with my early Cammer parts with the spark plug holes centered in the combustion chamber---and entering from the lower edge of the cam covers. That was theoretically the right place, but testing showed that the way it was soon-after done, off center in the combustion chamber and coming in from the upper area of the cam covers produced an extra hundred horsepower. So they were only good to look at.
It's possible to make enough torque, with what we know now, that that transaxle would simply shed all its teeth as the clutch grabbed. But...
