cracked plate

[Horace Greeley]

Hi, Gordon,

You might contact Robert Wagner at Pianotec about plate 
repairs.  Here is a link:

http://www.pianotec.com/Plate%20Repair%20Page.htm

With the background scene fairly visible, the pictures on this page 
are a bit hard to see, but you can get the general idea.

Hope this is of some help.

Best.

Horace
