I'll give you a hint about what makes me think I know which side is the shifter and which side is the brake:
When you are sitting on your bike, preparing to ride away, which foot do you have on the ground if you are on level ground?
Edit:
This fellow looks like he's about to ride away, and I bet he has the foot he plans to be shifting with up on its peg!
Of course I could be wrong, but I don't think so!
BTW, a couple more pictures of that bike that I scrounged up:
Well my goodness... all he has for instruments is a big old tachometer...
and the little bicycle speedo off to the left on the bars.
