Here's the Brooks saddles after some light surface sanding to smooth out the cracks and then treatment with Neatsfoot oil followed by Dr. Jackson's Hide Rejuvenator. The Dr. Jackson's is a product sold by the Tandy Leather Company and the counter person said it's prized for use by the horse crowd for leather tack.

I think they cleaned up pretty nice, although on the bottom one, the sides flair out a bit more than I like. It's from the girls bike while the top one is from the boys.

I'd say both are usable, if not perfect. I need to polish the metal bits and decided whether to keep the saddles with the Raleighs or use one on my daily rider and sell the other.
