I purchased a Brooks B5N at a bicycle store going out of business sale. The owner didn't know anything about it except it was part of the inventory when he bought the shop. According a knowledgeable sounding guy at the Missing Link Bicycle Store in Berkeley, it is probably a saddle made for Raleigh and sold as stock equipment on one of their models many years ago. The guy at Missing Link described it a low-quality saddle - but I like it. Jack McFarren
