Screw Stringer

[rchayden1@juno.com]

Apsco has the M & H wrench on page 10 of their supply book.   Part #
16150  (Note discrepancy in # beside picture....?)

You shouldn't have to grind it.   The let off wrench is next to it in the
picture, # 16149.

Plan on extra time tuning this, and charge accordingly.  They are an
interesting experience.  I have two uprights and one grand that I see
every few years, and they are always incredibly close to pitch, and
extremely stable.  

Question:  Is this one of those superior inventions that didn't make it
because of bad press?  I've never had opportunity to really care for one
of these in detail, faithfully.
