Woooo. Got some new toys in the post today.
A 1957 flare-tipped Gillette Super Speed, which is in lovely condition, and a 1963 Gillette Slim adjustable, which is in pristine condition as it has been stripped and fully replated with nickel. They both look the absolute nuts.
Had a shave with both earlier (one on each side of my face) and have to say they are both brilliant. Compared with the Merkur 34C, the blade angle is different and takes some getting used to. The shave is close and aggressive with the Super Speed, and the razor is light and compact - would make a nice travel razor I reckon. The Slim is the one I am really excited about as it is adjustable, so I can have it on one setting (I chose 6) for my face, but dial it up for my neck (I chose 4). This is really good, as I sometimes get razor burn on my neck. The weight of the Slim is much heavier in comparison, and it is weightier and more solid feeling than the Merkur too. I don't think I'll be dialling it up to 9 though - the blade gap looks like suicide!
The Super Speed is on the left and the Slim is on the right:
