|Close inspection of the photographs in this catalogue shows that the drums are all American, but they are photographed with Ajax stands and pedals.
In support of this observation it can be seen that:
The snare drum has the strainer, grommet and damper in the USA positions and the damper is clearly American.
The bass drum hoops are painted black (UK ones of this period would be silver). The inlay is Silver Sparkle and relatively narrow as one would expect of an American Mardi Gras drum (the UK inlay would match the rest of the Mardi Gras wrap and be much wider).
The script logos on the drums are the USA version of the time and shown mounted on the slant. The English Rogers chromed script logo was mounted horizontally.
The lugs on the small tom-tom are the “peanut” type, small bread and butter lugs, not seen on English Rogers toms, and which Rogers USA stopped using by the end of 1961.The legs on the floor toms are American “Statite” Rogers fittings available as a cheaper option to the more commonly seen knobby legs. Ajax tom legs are very similar to these.
These photos continued to be used with the 1964 catalogue despite the fact that whoever had set up the drums for the photos (probably a photographer) had put the swiv-o-matic tom arm in position upside down.
