These footrests came to me from a garage clearance. I cannot find pictures of anything like them. What you can't see in the picture is that the inboard end has a fine daisy serration presumably for adjustment. They have a part number cast in to one rest, A120/124.RX/2 MP A1(the M and P are vertical) They are 10" & 8-3/4" respectively. Could the MP be for Metal Profiles? And of course, they are for sale if anyone recognises them!
