If there's any place to post pics of typewriters and their guts, this is the place, IMHO. We all seem to love the little details that go into our keyboards. I don't see why this wouldn't spread to other related (and even unrelated) machines as well.
As an aside, this made me remember that I received an IBM Selectric II quite a few years back. It makes an awful noise when you turn it on, so it hasn't been turned on since. I don't know any local shop to send it in for repair though. I was going to look at it myself but since I don't have a need for it, it's been pretty low priority.
I would like to get it in tip top condition one day though. An electromechanical marvel. I love machines like this.
