Hi, thanks to all those involved in making this a very informative sight. I hope not all of you are bored with trying to identify old Gillette razors, because I just bought this beauty today but have no idea which it is. I think it is a Superspeed as the head is virtually identical to an American one I bought from Ebay, it has no patent numbers or anything on the underside. All it says is (Made in England) and Gillette in a kite shaped emblem. I'd love to know how old it is, so thanks in advance if anyone can help out.
