I bought this toolbox model saddle which was still on the original bike. It has taken me years to finally acquire one of these seats. I would like to do a minor restoration by replacing the sewn fabric "edging" around the perimeter of the seat as well as the "door". The leather on the seat is in good condition. Can someone recommend "the" person to do this? Also, the hinge setup for the door is not there so it just hangs off the back. What did these look like? At this point, it's important to get it right.
