Customer needs 415 Hz tuning fork

[A440A@AOL.COM]

Hi Ken, 
<<Does anyone know who will sell 1 fork not in a set. This could be a G# 
fork, 
but customer requested 415 Hz not 415.3 Hz for historical tuning.>>

     They would have to tell me at what temperature they wanted the fork to 
be when it produces 415, since this degree of accuracy requires a very 
specific temp.   Then I would alter a 415 fork to suit and sell it to them.
