Bates Foot Clutch Pedals

I can't say I had ever seen one of these Bates pedals up for sale until Jeremiah of Love Cycles sold the one in the last two pictures (pics from Love Cycles blog). I have seen the Bates 1955, 1962, 1965 and 1968-1969 catalogs and none mention this pedal at all. Possibly there is mention of the pedal between 1956-1961? If anybody has a catalog picture for this pedal I'd be very interested to check it out! (For Mo, here's a link to an earlier post with some more pictures on the Swedish knuckle as this is all I have and hope it helps. Pictures are HERE!)
