Will: I did some more image searching this morning and found this:

The Metaltek-ras appears to be the same machine. This company is not in India. They are in Akron ,Ohio. They do have a repair and calibration service. They may be able to help you with some written material if they are willing.
As a side note,I have a portable rockwell hardness tester. The image of that tool appears on the FIE site as well as this site from Akron. The tool that I have is quite old and was made in America. I was unaware that there were knock-offs. Good to know since I am missing the piece for doing brinell testing.
