Just visible on the headstock of this circa 1950/51 100 series (Mk. 3a) Clausing lathe is an Atlas badge. On the first Model 4800 lathes sent out after control passed to Atlas was an ordinary Atlas badge - their being no mention of Clausing at all. Unfortunately this backfired: previous Clausing customers resented the use of what they considered to be inferior branding and subsequent owners have been confused as to exactly which model of "Atlas" they have.
