My continuing saga of Super Speed comparison. On the left in a Gillette 1947 SS, in the middle, a Gillette 1949 SS and on the right from the same era an English made Superspeed or Rocket. The 1947 weighs in at 1.95 oz., the 1949 weighs 1.95 oz. and the English model weighs in at a hefty 2.25 oz. Notice that the 1947 has the older type blade bar with no notch, the 1949 has the sandwich bar with a large notch and the English appears to have a solid center bar with a very little notch. [vbpg]484[/vbpg] The heads (as with the Red Tips) are just a little different. Notice the side bar cover on the English model sits just a little lower. I believe that this gives the blade just a little different angle and just a hair more exposure. [vbpg]485[/vbpg] The handle length of the English SS is about 3/16" shorter than the other two and the bottom is enclosed just as with the Red Tip. This has something to do with the mechanisms different internal designs for opening and closing. [vbpg]483[/vbpg] Hands down winner as far as shaving goes is the English model, followed by the 1947 and then the 1949. YMMV I think the extra weight and the blade angle of the English model contribute to a smooth shave. That said, they are all good shavers, not too aggressive but just right. A good razor for a noob or an old hand.
