[pianotech] Accessing the Erard Action

[Phil Bondi]

Hi all.

I came across one today - a straight strung restored beauty, and I need 
to access the action.

The key cover has a long hinge connecting its 2 pieces at key height. I 
was not able to figure out how this key cover is secured. It is not 
secured to the cheek blocks - those came out rather easily. You would 
think from that description something must be holding it in place on top 
at the stretcher, but all that is there are 2 small #4's in a small 
brass lockish-looking device.

What is holding this key cover in place?

I took pictures, but for some reason I am not able to transfer from the 
Blackberry to the computer..

Where should A4 be set at? I'm thinking 434.

Feeling quite challenged today!,
