[GreenKeys] eBay Teletype Tools & Gauges - What Am I looking at?

[David Burns]

Will somebody who recognizes these tools please tell me what I'm looking 
at, and what they are good for.

1) At least this kit is fairly obvious..but is the droopy gauge damaged, 
or just so thin that it droops?

2) Tension gauge, and some weird hand-tools

3) Is that a contact burnisher in the background?

4) Poor photo, but a very strange tool in left-edge, middle..

Any insight would be appreciated..
