[GreenKeys] Spring tension scale?

[David Burns]

I recently purchased on eBay a 2oz spring tension gauge ("pull-only") 
made by Pelouze, that came in a Teletype Corp box with a bland TT part 
number on the side of the box.  It is entirely metal.

I also recently purchased three other spring gauges ("push-pull") on 
eBay, made by Chatillon for Teletype (Chatillon box, with a Teletype 
Corp sticker stuck on it).  These have plastic cases and are marked "Not 
Legal for Trade".

Chatillon is still in business, and this description of a Chatillon 516 
Series gauge looks very similar to the Pelouze version I own (except 
these are push-pull, even better).  It seems to be in the tension range 
that would be suitable for a lot of TT measurements.

 From a distributor here in MA that sells Chatillon:

At the same distributor, there is also a Chatillon 719, with larger tension:

Chatillon has distributors around the country:

Hope that helps.
