Comment I've provided images of two slightly different variations on the basic design, one with finer lettering/detailing (Variant 1) and open wheels on the cannons, the other with taller lettering and solid cannon wheels (Variant 2). A caduceus is the staff carried by Hermes (Mercury to the Romans).
As the name of the municipal undertaking was changed to 'Rotherham Corporation Transport' in 1929, it is almost certain that from the early 1930s onwards, tramcar staff would have been issued with uniforms bearing Pattern 2 buttons.
