A Raleigh Sports just moved into my basement workshop. Built at the Nottingham factory in May of 1977, it's been well cared for. I'm puzzled about the saddle. It's vinyl (I think), has a large letter "R" in the middle of the saddle and a metal "Rampar" name plate at the rear. The name plate looks exactly like a Brooks name plate. This saddle looks sort of low end to me. I'm thinking about some day replacing it with a Brooks B-72 leather saddle. What's the story behind this saddle?
