From Frank: These are Leaf Gaiters. I asked him right away when I saw these. I was told by him it was to protect the leaf springs from rust packed with grease. A quick story" when I thought I was all done taking photos and to have a cup of coffee inside, the owner showed me a presentation binder with all the historical documentation with the car dealer bill of sale invoice, Warranty Card, etc". It was a really amazing historical piece I really enjoyed looking at. However, I put my camera away back in the car so I did not take photos of this. He had the original company sales brochure and order guide however I do not recall the name of the company who sold them. I do know when he bought these leather leaf gaiters he also purchased from the same company a cover to the grill when driving in cold weather.
