Hello,
I'm considering buying one of these older Rockwell hardness testers. Our parts are small (think watch size parts) so I have been advised that the 3TT is the model that will work for me. A quick search on ebay shows some with the designation 3TTBB. Anybody know if there is difference between a 3TT and a 3TTBB?
Also any idea where I can find a manual for these?
Many thanks,
Ned
