Boxford & South Bend Backgear Shaft

Boxford & South Bend Backgear 24-tooth Shaft. We can supply - on a service-exchange basis - a backgear shaft fitted with a new steel gear. The large gear can be knocked off to save postage (though some early shafts were one piece). Early gears have a 14.5-degree pressure angle and have no markings to show this. Later gears are 21 degrees and in this case the shaft is stamped "21" - though it's sometimes hard to see. We can supply both types.
