It's beautiful saddle. I'm sure it's genuine and not a modern fake as someone cautioned.
You can tell from the quality of the perforated cover which looks very much like the cover on my white perforated Turbo saddle that I bought in the second half of the 80's. The modern reissue of the Turbo and Concor saddles with the perforated cover have a noticeable difference in spacing and perforation size, compared to the ones from the 80's. The really nice way the perforations on this yellow turbo saddle kinda swirls around the contours is hard to duplicate. The quality of how the saddle cover was glued on to the plastic base 8s what you'd expect from a Turbo saddle from the 80's. I really wish I had a Turbo saddle like that so I can install it on my 84 Gitane Pro that I'm finishing my build on, hopefully, very soon......
