[GreenKeys] Model 28 Typing RePerf

[Larry Tighe]

Howdy Don,

Jack tells me this is a universal problem.  I'm going to fabricate one using 
shrink tubing.  I'll create a bit of a bulge on the upper side using 
something soft and "shrink" it to the hammer position on the "handle".

I'm told all those hammers have deterioriated over the years and there are 
no spares.

Let ya know how it turns out...maybe some pix if it works.
