Hi there old car car guy... a great read this thread..
Noticed your piccies & text on the lathe a few pages back, I am from Colchester, England where they made that lathe


, & my father worked all his career with the lathe company (600 group) when they were in full swing.... until they shut the Colchester factory and then had to relocate it all up to Yorkshire UK. he spent alot of time on the drawing board in his early days before moving into management and is always interested to find out where the old lathes are now..
well i sent him some details & your pic and this is what he came back with.
"Good Grief - where did you dig that up.
It's a 7" lathe built for the American market. The rest of the world knew it as a Colchester Triumph 2000 (2000 rpm being the top spindle speed). Clausing were an American subsidiary of 600 Group and marketed the lathes on our behalf all were made here in Colchester. The two multi-coloured frying pan levers on the front of the headstock were manipulated to change spindle speeds. Quick-change is not quite right to describe it. The person describing probably thinks this refers to the quickness of changing spindle speeds but the expression really refers to the toolpost on top of the saddle. The toolpost fitted to this saddle can accommodate only a single tool was the most cost effective item that could be fitted and is not quick-change. A quick-change toolpost was a square block holding up to 4 different tools in toolholders at any one time. The toolholders could be changed very rapidly by the flick of a lever and any amount of tools could be used to complete a job at one hit. The lathe was probably built during the 1970's before we introduced electronic variable speed lathes in the 80's. Looks like its being put to good use...."
Just a little information for you...
