Finally riding a big boys bike
I'm looking for a special Huret downtube Shifter mounting clamp that was made in the '60's. It allowed a second shifter to be mounted opposite a braze-on rear shifter to convert a 5-speed to a 10 speed. there was a square cut-out on the right side that straddled the existing braze-on base. I cannot find a picture of one to post, I haven't seen one since the late '60's early '70's. Any help ? , or a picture would be a start.
