Made by the Turner Manufacturing Co. at their Wulfruna Works in Moorfield Street, Wolverhampton, these lathes were of entirely conventional design and manufactured during the 1920s and 1930s. Turner had wide engineering interests and, in addition to the manufacture of capstan and centre (engine) lathes, shapers, a useful copy of an American tool and cutter grinder, arbor presses and machine-tool accessories, were also involved in the motor trade having once been builders of cars and trucks.
It's entirely possible that Turner made machine tools for branding by larger agents and distributors who had commissioned a range (possibly from more than one maker) to be marketed under a pseudonym- a long widespread and still current practice in machine-tool circles. Just visible on the headstock of one lathe is what appears to be the word "GALTONA" - and other machines also show evidence of a name being erased, rather clumsily, from the catalogue pictures.
Although the lathes would have been produced in the era stated their appearance and features strongly suggest that they were based on rather older designs, though evidence of these has yet to be found.
Largest of the types listed was the 6.5-inch centre height by 33 inches between centres Model K; this was a backgeared screwcutting machine and available with either a straight bed or with what the makers described as a "half-gap"; in other words, a detachable section that was, in effect, a piece removed from the end of ways instead of, as was common at the time, forming a full "bridge" piece that completely filled the cut away section. Unlike the company's less rugged lathes the bed had underside and top parallel for its full length giving a more rigid assembly than used on other models. The "K" was also fitted with an auxiliary flat-belt drive to the power shaft to allow the generation of especially fine feed rates.
If you have a "Turner" lathe or other machine tool the writer would be interested to hear from you.
