Hallicrafters produced a couple of interesting 1948 sets. Their model 505 (
http://antiqueradio.org/halli505.htm) had push-button tuning:
The same chassis was offered in a metal cabinet that resembled a Hallicrafters SX-42 boatanchor (model T-54) and in a leatherette cabinet with a hinged cover (model 514).
The 1948 model T-67 was a better quality set (

Their 1950s sets were uniformly blah. I suspect they had low sales; I have never seen one in the flesh.
