<< Hi guys and gals,
 
 I just tuned an old Hindsberg with relatively new strings.
 Someone had put front rail punchings on the tuning pin for the left string 
 of every A.
 I´ve seen this before, and thought maybe, on some occasions this was left 
 over from some old tech that wanted to mark excessively loose pin, or 
 something.  There was, however, nothing wrong with the torque of any of 
these.
 But why on all the A´s?
 
 Best regards,

After stringing a piano, marking the A with a punching will help with the 
chipping process.  I don't it myself, but I have heard of other doing it this 
way. I guess the stringer just never bother removing the punchings.
