Key levelling device - APTTA

[Kerry Cooper]

Phil,

APTTA stands for 'Australasian Piano Tuners & Technicians Association'. 
PTTGQ stands for 'Piano Tuners & Technicians Guild (Qld) inc'. This is a
State guild and like every other state in Australia, had been established
before the APTTA which was first only unifying all state guilds into one
national organization and the national voice to Government and piano
wholesalers.  The state guilds retained their own independent identity.  

The APTTA now includes New Zealand, hence Australisian. More info is
available at www.aptta.org.au.  We hold our conventions on a bi-annual
basis, the last was July in Adeliade where we were graced with the presents
of Roger Jolly and Ron Nossaman as lecturers. Our next convention is in
Geelong, Victoria in 2006 followed by Queensland in 2008.

I am currently the President of both the APTTA and PTTGQ.

I hope this answers your questions.

Cheers

Kerry,

I have some pictures of this action around some place, although I 
can't seem to lay my hands on them at the moment?  Was the key 
leveling screw accessible with the action installed?  That's the 
beauty of Mr Perry's device.  By the way, what are APTTA and PTTGQ?
