Gentlemen, you know British Gillette razors have always a big mystery for me. Different cases, minor design changes and dating them are sometimes difficult. Well, I have two different designed No. 81 with two different cases. First one is a 3 piece version and its beautiful chrome case. It weighs 73gr and its length is 84mm. But the other one is a 2 piece like No. 77 and No. 88 with Richwood case. Its weight is 75gr and length is 82mm.
I added few links from the past which are related this variety issue and model. Besides 2 piece No. 81 was not restored, imho. In addition they share the same patent number. BRIT. PAT. NOS.-352975-6-7-363892
Sorry for my bad pictures.
