Since the White House recently released a picture of President Obama firing a shotgun, CNN posted a gallery of Presidents and guns.

Something caught my eye in the FDR picture. The caption is "Franklin D. Roosevelt fires at the Marine Corps rifle range in Maryland in 1917." (He was Assistant Secretary of the Navy at the time.)
What's that gun in the foreground? At first I thought it was a Japanese Type 11 LMG, but the features don't match, and the Type 11 didn't come into service until 1922 anyway. Any ideas?
