I just purchased a 1964 Aristocrat adjustable. This was my first shave with this razor. I put it at setting 6 as I do very often with my Slims which I believe are the same razor except for the finish. The going was so rough I didn’t finish the first pass. I put the blade in one of my slims at the same setting and the shave was smooth. I wonder what’s up. I looked at the two razors and noticed that when I looked down at the doors with a blade in each razor the Aristocrat had noticeably more blade showing at the edge of the doors. When I got the razor the extra quarter turn was not smooth going. Also when I open the doors there is a slight bind after I get past the quarter turn. I did the soaking and exercising the mechanism with the hot water and Dawn trick. I also tried WD40 and sewing machine oil. Things improved but it’s not like my other slims. The quarter turn could be smoother and I still have that slight bind when opening the doors. Here is a couple photos. They’re the best I could do.
