First diesel chainsaw in the world....This is the third model WITH AUTOMATIC REWIND AND PRESSURIZED GAS TANK
Very light and innovative saw.... but sales were not what the inventor Mr. Wiig had hoped for, so, he took his idea to Sweden to a company called Como..later to become Jonsered/Huskvarna with the model "P" (propane or prototype??)as the fourth model. Fifth production model was the Jonsered XA . M.T.Bjerke would build the Comet in Sweden. This occurred around 1950. The Swedish Comet was called model B. Swedish production of the model B Comet is approximately 1,000 between 1950 through 1953. Very light saw, 32oz would make her run for 1 1/2 hr....It is a 2 cycle engine that uses an injector type of carburetion system. The glow plug called a tandror works using propane gaz under pressure inside the handle assembly.
