Named 'Surfmaster' as id'ed by Old Ticker via crystal dimensions and description
The name listed in the 65 GS catalog for 1166E is Surfmaster "A", and the GS part # is CMS660.
The measurements are slightly different in the GS listing verses the Original Bulova specs, 23.1mm x 23.1mm and 25.1mm x 25.1mm flange compared to what the Bulova crystal shows, but they both have the 1166E model number on them.
This may be a "Surfmaster" in 1957 and renamed Surfmaster "A" in the later years?
