I agree, that is a great pic!
Its motivated me to get back to restoring my own TA.
They are so tiny they can be displayed anywhere in the house.
I couldn't afford an old board tracker so I figure a TA is about as close as I'll get.
Plus, I think they have the distinction of being the first factory GP bike for club racers.
Many years earlier a Manx had been as close as you could get, but they died off.
