There was discussion here about these a while back.   I've tuned a few of
these, both grands and uprights.  The pin torque/feel was a little tight,
and a little strange, but tunings went normally.    A colleague restrung a
little Apollo grand; as I remember it, he had no unusual problems during or
after stringing.  I tuned that piano 20+ years after the restringing, and
everything felt and acted normal.  Had I not recognized the piano, I
probably wouldn't  have even been aware of anything out of the ordinary.

I sure would hate to lose those tuning pins, though.  Until they're back in
the piano, guard them with your life.
