Text reads: ‘New Danarm direct drive chain saw Model Do.B.R.’
Note the engine crankshaft is now in line with the sprocket drive and the tank and carburettor are now in a fixed position on the frame and starter cord is on a rewind spool. From memory the carburettor was a Tillotson diaphragm version. Oil may still have been pumped by hand and total weight was around 28 lbs.
Any more details and experiences very welcome.
