Hi Ger ~
Sounds like you got the desired result, straightening the limit pin.
A badly bent limit pin certainly could cause poor tracking and
possible excessive wear. The big counterweight would be forced to
track favoring one side, which in turn would put the diaphragm link at
an angle, risk the pin rubbing on the edge of the limit loop, cause a
sideways scrape of the diamond across several grooves when the
reproducer is set upon the record and removed, adversely affect the
automatic stop, etc.
It sounds like you might be lucky and have a nicely preserved
diamond. The diamond is as hard as .. diamond, so it takes a long
time to wear out in normal use, BUT being hard, it's also brittle and
can be fractured if the reproducer drops abrubtly to the record
surface (from mishandling the control lever), or from striking
something hard just the wrong way.

Hi Andy,
Great insight on the stylus as a possible cause for damage...thanks
I see a shiney smooth point in the diamond area...overall, kind of
triangular where it's sitting. I used a 10x loupe.
HOWEVER, what I did notice (forgive me for not knowing proper
terms): the small metal prong which is most forward in position on
the reproducer, and sits in a V-shaped hook from the top (it goes up
and down and side to side). Anywho, this prong was BENT to one side.
I just straightened it, or at least got it to move symmetrically.
I'm guessing that that bend might make the thing track badly,
possibly causing damage to the record grooves??
