One of the members at SMF is in the UK. He contacted Harris just a few days ago and it happened that the Windsor had just then arrived at Harris's brick and morter store in London. He was told there will be a soap, but it hasn't completed the manufacturing process, and will be along at a later date. As far as I know, it's so new it hasn't had time to be distributed to vendors. The SMF member bought a sample of the shaving cream and has posted about it on SMF. His review was positive.
. . . He went around back and into the basement because he was hungry. He ate cold beans out of a can and drank some water, and then he saw the small mirror Parker had bought with the razor and the can of lather. He looked at himself and knew he had to take a chance on staying long enough to shave. He shaved, and that made him feel better. . .
