Patentee of this attractive little machine was the London engineer Joseph Margulies Landon. The patent plate lists UK Patent 10817 for "Improvements in the Construction of Talking Machines and Cases therefor." It was granted on 6 June 1913. Landon's next stroke, UK Patent 153948, "Improvements in and Relating to Gramophones", for an improved guide rod, was granted on 15 November 1920. This limits the production of your machine to the years between 1913 and 1920.Steve wrote:I think this design might date from 1908-ish but does anyone know for sure?
I don't have a drawing of 1913, but here is one from the 1920 patent. Does "your" guide rod differ?
