When was the Model 36 MoPar Deluxe Heater used?

The model 36 is pictured in the 1946 accessory brochure, I suspect it may have appeared in 42. I think that syle with the motor through the horizontal horse shoe core was used from 39-48.

I pulled a nice Model 36 MoPar Deluxe heater off of a 30-U parts car last year and am wondering what era of Chrysler product it would have been stock on?
