I picked up a mahogany boxed set from our Labs cleanout day. It had inside what appeared to be glass hone blocks, a cloth block with a device that tightens and several bottles of white powder.
Research and Industrial Instruments Company, England was on the outside of the box.
The only info I could find is it some sort of lens polishing outfit.
Anyone here use glass honing blocks? Can they be used for straights?
