|In November 1935 the newly redesigned sawset #42X was introduced and continued up to the Spring of
1948. The 42X is different from all the other 42s. It has a dual plunger. There is a larger, round plunger that activates first and grabs the saw blade. Inside the larger one there is a smaller one that activates next and does the setting. This makes for a more positive set with less effort.
