I just bought the razor below. Now this is what I call a slant! I've measured the angle of the head to around 35 degrees. The manufacturer is Sesam, a Swedish company about which I don't know very much. I assume it dates from around the 50s, but someone else could probably fill me in on that.
The head is in white/cream bakelite, and the handle in dark red bakelite. The head is attached to the handle via a stainless steel attachment, and comes off for opening/blade replacement.
The razor isn't heavy, but it does have some weight, concentrated at the top of the handle, so I think there is some metal inside the handle.
It came in the original box, with three different original Sesam blades, one "Rostfria" (stainless), one "Gold", and one "10 Luxe". It seems that the razor has never been used. I'm very curious to see how it shaves.
