Olympia SM4

This is what the machine looked like when it arrived. It's difficult to see the mildew on the keys from this view.

Mildew covered keys.

After cleaning, not perfect, but not filled with dirt.

This is explained in detail in my August 9, 2013 post

There are several cracks similar to this all over the platen

Olympia's unique method of keeping the key tops parallel to the desk while typing.

Rubber grommets and washer from Ace Hardware

These are the springs that adjust the shift tension.

I have these pulled quite taunt with a bit to spare

I used a dial calipers to set both sides the same.  Counting the exposed threads will work fine too.

The vinyl on the case was in bad shape and peeling.  I removed it and left the wood as it was found. I was going to sand and re-varnish it, but it looks fine as it is shown.

Hint. Look at the end of my workbench -- previous post.

Thanks to Nick Beland for the escapement rail information.

 I have many more photos taken while this machine was being repaired. I may post all of them directly to the typewriter repair site Nick is building or post them all here in a future post.
