I know this isn't exactly the most appropriate thread for this forum but the appraisals seem to be the closest fitting.
I'm looking at getting a used Brooks. He's willing to part with it for $60 but if you check out the pictures the underside looks as if it's been wet. Could this be from sweat or is it most likely from rain? The guy who's selling it says he got it off a bike he picked up so he's not the original owner of it.
I know I would check for things like dryness, mold and general sagging type issues but beyond that I was just curious to see what you guys thought, especially given the price.
