Went to look at a bike yesterday and the guy starts talking about selling stuff and we're looking at a Raleigh Sports he's working on that has a nasty saddle on it. He says he's got this nice leather one that he's been trying to sell on CL for a couple weeks for $50 and shows it to me. It turns out that it's a very nice Japanese leather saddle that looks a lot like a B17 and it's in very good shape with no noticeable deformation but just some scuffing that I would call light. The photos in the CL ad don't really show how good it is. Leather seems to be pretty much pristine with no noticeable cracking or pulling at the rivets. In the photo of the underside, you can see what appears to be a plastic support that I'd guess is designed to make sag less likely.
Don't know if this is the saddle that came with the early 70s Fujis or not, but if anybody is looking for a nice brown leather Japanese saddle in the style of B17 this would likely suit.
Forgot the brand, but this guy posts his number in all his Craigslist ads and he likes to talk bikes and everything about them. He likes it a lot.
I have no interest in this, by the way.
