The Hahn Cab and chassis built in 1972 to 1983 was a copy of the previously used Cincinatti cab.
Because the cab was designed in 1970's, it had a wider cab then the older 1960's Cincinatti cabs. One outstanding feature was that Hahn added the eyebrow overhang above the windshield.
Also Hahn designed a new cab (84-92) in 1983 extending the jumpseat area see post #694 page 35 of this thread. There were only a few of these built. Soon after the 84-92 cab was for sale the Hahn 92 cab (92") was available. A few of the two older designed cabs, (84 and 84-92) were still sold after this time.
