Jigby,

Here is a picture of a manual Brinell tester. Not the oldest (try Detroit Testing Machine) but trust me it is old.

I've been trying to find a picture of me operating a very similar hardness tester, probably an earlier model than the one posted.
The foundry that I CO-OP with had these machines on foundry floor for a quick check on test bars to make ladle or air furnace adjustments. One could take a chill bar and a hardness check and hit the physicals for cast and malleable iron without any problem.

Are you mentioning any of the other testers, like the Scleroscope?

I will be interested in any pics of older type Brinell testers and any other types of machine.
I am currently writing an "introduction to hardness and hardness testing" as a 100 slide power point presentation for students - and I am describing the development of testing - this does include the scleroscope (which I have never seen face to face!). I would be interested in any information on the subject.
