Scored this today out in the wild. The case is very plated, but the razor itself is gorgeous. Since there is really no dating info on the Canadians, I have no idea on that one but the serial number is 352368 and it has the diamond logo so therefore it would be later than 1910.
As seen in other threads like this one I too have an odd understamp. I think that it is shadowing from all the other razors that were stamped by the same machine.
