Huge thanks for the help.
Machine is clean everywhere.
Mechanisms seem to be in order. Nothing disconnected or bent or missing.
The "hook" shaped thing beneath each spindle moves when the rubber baby bumper tab is pushed all the way, but the spindle direction isn't activated until the hook is further depressed by hand.


There is a cross link stiff wire that connects both spindles via this end mechanism, shown here with the top of a pin fastened with a ""C" link. If that is pushed either all left or right, then the direction of the spindles do indeed change.
But, I don't see how that motion is effected by the; rubber baby bumper tab, or the "C" hooks below the spindles, or the movements (none) of the ribbon guides.

so, at this point, I'm lost at what to do. The ribbon direction at least can be changed by pushing those end pivot blocks that are connected with a long cross link/wire to each other, from either full left or full right. Beyond that, including the rubber baby bumper tab, there's no other way to reverse direction. Short of just flipping the ribbon spools.
Do you have any ideas on where to look or what next?
Huge thanks again. I'm new to all this so sorry for the lack of terminology on what things are called on a typewriter.
Aloha
