1918 Navy, Again ;]

[tracyp]

I mentioned in a early post that Ralph Shattuck had a 1918 Navy for sale and I saw it. But in all of the books that I've read there are no known 1918 dated Navys. In John Walter's "The Luger Book" he states that the only 1918 dated Navy reported was believed to be mismatched Army P08 receiver. Has anyone else seen a 1918 Navy? If so, do you remember the serial number.
