The 89 first came out in January 1933 - but it was originally an AM-only, 3-knob set. This one is a later 4-knob model with AM and the "police" band. That change was made at the factory on March 15, 1933; I do not know if the newer two-band 89 sets made it to the dealers prior to the new model year start-up in May-June 1933, or not. So the earliest this cabinet would have been modified for use with the 4-knob 89 would have been sometime in the early spring of 1933.
