Another contrast with postwar: With postwar, you can get the worm and gear by themselves. With the modern [rhymes with snap], the best you can do is get an entire axle and an entire motor assembly.
True for the 773, and F-units with horizontal motors. For everything else, the worm was cut into the armature shaft (and not all armatures were alike.) Not arguing, I agree with you! This is one of the pet peeves I have with a lot of modern-era designs. Even the new Legacy brass hybrid has the worm pressed onto the motor shaft. Transferring that gear to another motor will be difficult or impossible. So the "spare part" I was thinking of is a motor complete with worm and flywheel.
They made enough of these baby Berks that cannibalism will be a viable strategy 20 years from now. Some of the rarer, more expensive items made this way will end up as shelf displays
