1914 dwm

Dick,
I would think the deep and large date on the chamber would be tough to change without its being noticeable.

You are right about the 1915 artys, they also have the triple c/s proofing, at least in the early numbers. I recently sold a 3 digit 1915- which except for the "4" in 1914 was identical to the 1914 dated ones.
