Thanks for the guidance and advice.

This is one of the few Brooks saddle models that I've never ridden. I'll probably just run it with the original included mount/clamp and a traditional straight post. I'm not concerned about weight. It will be ridden casually, aka, "Riv" style. I don't see myself mounting those massive springs on my Paramount.

I also want to see what I can do to restore the appearance of the leather and to strengthen the places which are cracking.
