The "Turner" range of machine tools encompassed ordinary centre lathes, capstans, shapers, arbor presses and a useful tool and cutter grinder. The history of the company is not known and the only surviving literature has the word Turner in parenthesis, a sure sign that this was not a manufacturer but a marketing ploy by a larger agent who had commissioned a range of machines (possibly from more than one manufacturer) 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 could have been produced until the late 1920s (and that is the era of the documents their adverting literature was found amongst) their appearance and features strongly suggest that they were designed in the late 1800s or early 1900s.
The largest lathe 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" the writer would be interested to hear about it.
