This page documents what we know about Gillette Canada safety razor serial numbers and date codes. Razors made in Montreal often left the factory with serial numbers or date codes. During certain periods some or all models were unmarked. In theory any markings can be be used to establish their manufacturing dates, but at the present time our knowledge of the Canadian markings is spotty.
One estimate is that the Montreal plant made "no more than a few thousand razors in 1906, and then maybe crossed into the 5-digits in 1907. If we assume that the plant was operating at that same production rate six days a week for the entire year, they'd have been turning out somewhere between 20,000 and 25,000 razors a year."[1]
