I don't know what the point of the pix were but I see very little or no similarities. What you did manage to show is my all time favorite bike. My dream bike to be sure. I always wanted a 1937 Speedtwin. (same as 39) What a beautiful machine.

I learned all I need to know about life by killing smart people and eating their brains.
