It's a long, long time ago but there were two brass pipes with taps simply dripping oil onto the face of the diamond facing.
There were, if my memory holds out, tool guides and there was a table capable of being tilted to hold tools. At that point there was no such thing as inserted carbides and so on.
Date? Perhaps 25 years ago and the venue at Gateshead Technical College. I sort of 'did' Model Engineering in an evening and a City and Guilds in Motor Vehicle Restoration as a day time manure student after retirement from the real world.
Really, the tool is not much better than a basic homemade Kennet- which I made up from part machine castings and is in the second division compared to Quorns, Stents and Clarksons which all have versatility. My opinion of course.
Cheers
