key sticks

[David Love]

Don't know for sure but I think they probably just drilled for the front
rail pins in the wrong place.  Afterall, the location of the pins is
meaningless except that it centers under the mortise.  Another good
plate indexing job too that got the capstan back far enough that they
needed seven keyleads at F1.

I'm sending along 2 pictures of the F1 keystick, B 342631. Note the 7  
original key leads, and the non-original leather key bushings. But  
why I'm writing is the interesting location of the wear in the key  
bushing from contact with the front rail pin. The whole set of keys  
is similar, and under certain circumstances the front rail pins do  
indeed bind on the front of the mortise. (This explains a few things!)

Any ideas out there with regard to what happened? It looks like the  
mortise is in the wrong place by just over 1/16". Anything else to  
watch out for? I know, I know -- watch for  _everything_. But it  
probably is just the mortise in the wrong place, right?
