I don't know. We didn't find one, but it certainly could
have escaped. The shop adjusted the bearing, but I don't
know if they took off the nut to check on the D-washer.

Dunno. Didn't recover it.

I think so. Maybe. I don't remember. We recovered the
nut itself.

The rollers and races were pretty-much scattered to the
winds.
There was considerable bluing on the spindle. It has been
replaced by one from Joe Alexander.
