1930's? Triumph side valve single?
« on: January 24, 2008, 11:52:23 PM »
Hello,

This is my friend's grand father's Triumph.
He claimed to be one of the first three Triumph owners in Japan.
The only thing my friend has now is this photograph.
He wants to know model/year.

Thanks!

It's either a 500cc 1931 Model CN or a 550cc 1931/32 Model CSD. Only the engine number and the bore sizes were different and I can't see either!
