The funny thing is the cylinder itself has an entirely different key code stamped on the back of the cylinder in numbers. Searching on the Internet turns up no info about these. Apparently the only pictures are of a few that have shown up on eBay, nothing else. Im going to assume they were not produced for very long just based on their apparent scarcity and the absence of info about them.
