Manufactured by a Swedish company, Högboholms Mek. Verkstad 340 37 Torpsbruk, the Högbo Model 75 lathe was based on the American Atlas 6-inch (though with a longer bed and, on later versions, with the addition of a front bed V-way for the saddle). A product of the late 1940s and into the 1950s, unlike the American model, the Högbo used plain instead of roller bearings for the headstock and was, in that respect, identical in specification to the cheaper version of the Atlas offered by the mail-order company Sears under their Craftsman brand. However, instead of simple plain bushes, nipped into adjustment by a split headstock sleeve, the Högbo employed a very much superior design, the substantial bronze bearings being threaded on their ends and drawn into tapered seats by opposed adjustment rings.
With the expectation of sales running into the hundreds of thousands, Atlas had invested heavily in expensive moulds to produce many larger and smaller components - including the changewheels, backgears and leadscrew clasp nuts - in pressure-injected ZAMAK, a form of hard-wearing zinc.. Surprisingly, Högbo, despite having a smaller and (at the time) less-affluent market to sell into, also chose the same material for some minor parts, though major items, including all the gears, were made from conventional materials.
At first, a standard bench-mount model (shown towards the bottom of the page) with a traditional, rear-mounted countershaft was offered, this being followed by one sold complete on a rather fine, pressed-steel underdrive cabinet stand with tall, cast-iron raiser blocks under the headstock and tailstock. The headstock-end bed foot was used - rather neatly -  to mount the electrical reversing switch.
Based on the examples so far discovered, the lathes appear to have left the factory painted in bright red enamel.

If you have a Högbo lathe the writer would be interested to hear from you.
