I'll be honest, at that point I think it would be cheaper to just locate
another Model M somewhere from the internet that's missing keys or
something and rebuild it up. Finding the support frame will be darn near
impossible alone, and I've heard putting the membrane back on properly is
about as hard as putting a spacebar back on a Model F.
If you don't mind me asking, how far did this one fall? I had one fall off
a 7 foot high shelf and survive with a couple key caps knocked off, but
that might have just been luck.
