I just won a British Aristocrat Junior from @Hannah's Dad in the fundraiser. Having shaved with it several times now I find that for me it has very much the same shave experience and performance as my Gillette Ranger from the same era. The knurling on the Ranger is just a bit more prominent and gives a measurably more secure grip. The Ranger was only made for a few months at the end of 1941, before the Pearl Harbor. My British Aristocrat Junior was made after the war, about 1950 from what I read.
