[GreenKeys] TT-7/FG Restoration

[William Wuttke]

 Two more frozen parts:

- Front spacing escapement pawl.
- Carriage return operating lever.

The Greenkeys list archive helped me with the spacing problem. Gil Smith had the same
problem many years ago. 

Now it's typing like it is supposed to.

  Hooray! Almost there.

After unfreezing a lot of parts, cleaning, and lubrication, I finally put everything
back together for a smoke test. All keys pressed print the correct letter. Line feed
feeds the line. Figs and Ltrs do their job. Ribbon winds.

However.....
- It sporadically prints an extra space after printing a letter.
- Carriage return does not return the carriage.

Tomorrow is a troubleshooting (and hopefully, repair) day. Probably need to
unstick something else. Maybe some lubrication I missed. (Virtually every
roller was frozen. The main shaft cam unit was frozen - needed to use a
heat gun to get it loose.)

(Keyboard still needs a good cleaning. Punch still needs proper testing.)
