Colin,
You mean the eBay listing 201579670900? Does not look anything like an EW brake pedal.
I am not sure what a touring model would be. Often this was a euphemism for a model with foot boards rather than footpegs, larger section tyres, or a colonial model build a little more heavily than the standard model. So the first touring EW could be the B28 (A28 had footpegs) or the H3, and heavy flywheel version with sump in 1930.
I did once see what was purported to be an EW Deluxe, gold lining on the tank panels and deep section mudguards. So not everything necessarily made it in the catalog.
The Sports certainly did. Its distinction over the Standard EW was aluminum pistons, specially tuned engine(!), drop handlebars, twist grip throttle, steering damper, and road tested to yield 65mph. I have been told the Sports was the first 350EW to get the detachable head, though the first mention of it in the general catalog is with the B28.
