Another interesting item in the 1957 Berg’s Truck and Parts Co (Aka the King of Jeeps) Catalog was this “Jeep King” hardtop advertisement, for both half and full-size tops. It looks like it’s a private branding of the Beck (or Kemco) Jeep Cabs, because the door has the split window. As far as I know, that wasn’t available on the Kelly hardtops manufactured by Kelly Manufacturing (which is the company Kemco became).Also, the Kemco had the small window on the half cab, as does the Jeepking half cab.
