Mike Arrington got it right! I wish I could give him a prize. All I can give him is my thanks.

It was the typebar guide. I could not find directions to replace a pullbar so I had to figure it out myself. The best I could do was remove the guide/ribbon oscillator so I could hyper-extend the "S" typebar to remove the  broken pullbar and slip a good one in. It took some trial and error to get the teeth meshed right so when the "S" typebar was on the rest the pullbar lined up with the others.

I put at all back together and that is when my uneven baseline started.

The guide adjustment turned out to be super-critical. Once I got the baseline straightened out today, I had to do some gentle typebar bending so none of them would stick.

By the way my "Z" is lined up but is still printing light on the bottom.

I am wondering if the type slug is worn. Except for that minor problem, the 15 looks great!

I have a parts carriage. I could take the "Z" from that. Where can I find instructions for replacing a typebar correctly?

Thank you Mike. There are so, so many things to learn about fixing Teletypes. I learned a new one today.
