While this is quite likely a 1963 or later model, be aware that there were sets made in the 1950's with factory UHF.
These sets were offered at a higher price than VHF-only models, and were usually hard to find, unless you were in a market where all TV was UHF (e.g. Fresno, South Bend, Youngstown) or there was only one VHF and more than one UHF (e.g. Austin).
