Although some claim that the M23 is a 'rock crusher', it is indicated that this box was assembled in both wide and close ratio components and also with straight cut gears common to the rock crusher (M22) transmission. Looks like you have a second design-feb. 28th, 1968, M20 or M21. Definitely not a rock crusher(no straight cut gears).
