The semi-cathedral cabinet option for the 1936-37 range.
Sets available in the Cambridge cabinet, according to the Johns catalogue:
Companion 55 Broadcast (5-valve AC or DC)
Companion 55 Dual Wave (5-valve AC or DC)
Companion 65 Broadcast (6-valve AC or DC)
The photographed model from John Stokes' photo archive is noted as being a 6V DW model (not listed above). Also note the knob layout is different to the catalog image - probably a different year? The dial looks slightly smaller to accommodate the layout.
General Construction Notes for Wellmade Ltd: Radios made for Johns in the 30's were often available in AC, DC or Battery. DC, because large tracts of Auckland (where Johns and Wellmade were situated) were powered from DC plants.
