Nice to see this thread back on page one!

I guess this would fit here as well. Not a step-through in the strictest sense, but designed for people who wanted the riding qualities of a double diamond frame as well as a lower stand-over height. With those same people in mind the frame was also made a little shorter than the average double diamond frame.

Designed in the seventies by the then twenty-something Francis Quillon for Albert Metayer's Méral brand and patented, so it couldn't be copied by other manufacturers.
