I found the answers to my own oil pump questions in my new reprints of the Book of Information p.53 and 57, and, also in the Mechanics' Instruction Manual p.120. The 2 brass blocks are called vanes; the springs in the end of each vane press against each other to keep the vanes to the outer housing wall; And the little ear of metal that I tho't was a random shrapnel or slag is actually a key !! that is part of assembly of impeller to shaft. That part I haven't re-assembled yet, but thank goodness I saved it.
So the lesson learned is, I didn't know the oil pump is supposed to stay assembled to the pan when lowering it.
One of the tiny springs in one vane is damaged - thinking maybe take it to a clock or watch repair guy to find a replacement? It just fits into a hole bored into the end of the vane. Tiny delicate spring; the other one looks near perfect. Amazing. PS I still haven't unstuck my pan yet, wish me luck I don't bend it. Texas Jim
