A Forum member was after information about the rack feed tailstock designed by Martin Cleeve (Kenneth Hart), I contacted him as I have one of these. It was suggested others might like to see the tailstock in question. so I have posted some photos in my album, unfortunately they are not very good but the best I can do for the moment.
This was purchased by a late friend of mine from Martin Cleeve's widow along with a front swing clear retracting toolholder, a rear swing clear toolholder and an ML7 lathe he was modifying for a friend when he died. I do not know what happened to the lathe.
I also have Martin's "Machinery's Screw Thread Book".
Pictures of all three tooling items can be see in the Workshop Practice Series No3 "Screwcutting in the Lathe" by Martin Cleeve.
