Not a manufacturer, but a company that re-badged lathes and other machine tools - in particular bandsaws. The "DoALL" lathes shown here were manufactured during the late 1960s onwards by the Harrison Company in England. The lathes are a mixture of the first of a series of new and very different machines that replaced the older types from the 1950s and 1960s - and also the even later "M" range. The 15" model at the top of the page is one of the first of the "early-modern" type and was also offered with a 13-inch swing. The second lathe below (badged as a13-inch)  is a Harrison M300 and that shown as a "DoALL 17" is a Harrison M400.  DoAll also sold a 16.5" machine - the  Harrison M450 & M500 as well as one rather odd model, a combination of the early "11-inch" and its replacement. Harrison lathes badged as "DoALL" can also be see on this page.
