CRYSTAL CALIBRATOR FOR WS 19 BY CANADIAN MARCONI DATED 1943
On offer today we have a very nice example of a Canadian WS19 calibrator. Unlike some, the screen printed legends on the side are perfect and the paintwork is good. On slight detractor is that the screened lead with Eye socket connector has been replaced in the original chassis orifice with a screw terminal but other than that it is original and no hacked about. In all a scarce piece of kit and one in smashing order.
