What is this marking (1916 DWM)

I checked Wikipedia and several other sites to see if "copper-nickel-chrome" is still used. "Copper Nickel Crome is still a common process for quality plating over ferrous metals.

http://www.verneschromeplating.com/index.html gives a nice take on it
and
from Wiki plating
Chrome plating[edit]
Main article: Chrome plating
Chrome plating is a finishing treatment using the electrolytic deposition of chromium. The most common form of chrome plating is the thin, decorative bright chrome, which is typically a 10-μm layer over an underlying nickel plate. When plating on iron or steel, an underlying plating of copper allows the nickel to adhere. The pores (tiny holes) in the nickel and chromium layers work to alleviate stress caused by thermal expansion mismatch but also hurt the corrosion resistance of the coating.

My point was dismissing "Chrome" as "Bumper guns" is clever but neglects the realities of the process. I own one chrome plated beauty and I will see if I can hunt up photos.
