Ok here are some pictures. The first 2, the one in question, is a B66. It cleaned up very nice and the last application of Proofide left a finish similar to the 2nd newer one. A minor nut adjustment toned it up so it doesn't sag on the frame. If you look just above the shiny nut you can see the embossing in the leather from contacting the frame.



This 2nd is a Champion Flyer and seems much newer Only needed one application of Proofide and still pretty stiff. No nut adjustment needed at this time.
