[CW] Restoring a 1943 Tin dataplate

[Valery Pakhomov via CW]

Hi Stan,

Will you look through the book HOW TO RESTORE TELEGRAPH KEYS by W.R. SMITH. There
is a lot of useful and interesting information there.

  Hi all. I'm restoring an old Vibroplex and when I got to the tin plate,
  I started with the least abrasive method (soap, water, toothbrush) and
  progressively became more aggressive - vinegar and water, Simple Green ,
  Coca-Cola, Brasso, and a metal polishing paste. Overall, it looks good
  except there is still the darkness (dirt,rust?) in many places like
  inside letters and numbers.

  Does anyone have any suggestions for further improvement?

  73 and Season's Greetings,
  Stan WB2LQF
