A Mystery Repair

I thought a bit of photo forensics might be fun.

Typewriter A, made in 1921, has a broken thing-a-ma-jig, (TAMJ) and the carriage goes all gahooey when the shift key is pressed.

Ga-hoo-ey, adjective, having become no longer in working order or functional, i.e., disfunctional.

.

Typewriter B, made in 1929, with unbroken TAMJ, and in reasonably good functional order.

.

The broken TAMJ from typewriter A, and its tiny, unique screws, which I was in a terror that they might escape to hide among the fearsome dust bunnies beneath the work bench. Note that the method of attachment and pivoting, as well as the holes at each end of the TAMJ, are different from one another.

.

The trusty canvas bag of brass stock inherited from my father. He acquired it during WWII (likely not an easy task) in support of his hobby of building model railcars and track. 

.

I've managed to get those holes drilled to the correct diameter and distance from each other, and am beginning to shape the new part.

.

Ta-da! Here it is. But wait - although the holes are the correct size and distance apart, it does not have the jaunty curve of the original.
WILL IT WORK?
Stay tuned ...
