Nothing is know of the origins of the little N.W. lathe save that it appeared, priced at £2 : 15 : 0d, at the 1923 Model Engineer Exhibition in London on Stand No. 1  taken by the distributors Thorn & English, Engineers and Tool Merchants of Chandos Street in Slough.
The N.W. was 18" long overall. with a 12" bed, a 23/8" centre height, could hold  8" between centres and, unusually for a cheap, small lathe of the time, had a hole though its plain-bearing headstock spindle--though only of 3/8" diameter. The simple carriage was driven along the steel-bar bed by a 3/8" diameter Whitworth feedscrew with the single slide rest swivelling on top of a round boss. The headstock pulley was designed to accept a round leather belt but the distributors offered no countershaft or other drive system, thought no doubt the sort of impecunious enthusiast at whom the lathe was aimed would not have found it too difficult to make one up from scrap.
If you have an "N.W." please do make contact.
