Badge: Shipbuilding War Service

The United States entered World War I in April 1917. Within days, the federal government created the Emergency Fleet Corporation (EFC) to construct a fleet of merchant ships. The EFC hired the American International Shipbuilding Corporation to build and operate the largest shipyard in the world: Hog Island, near Philadelphia.
This badge identified the wearer as a member of the World War I Hog Island shipbuilding team.

I have one of the war ship building service badge and i would like to know if there is a way to tell if it is ww1 or ww2. The # on back is 147650.
I found one of these Badges when I was going thru some old stuff that I had. I remember my father telling me that he was an inspector on ships when they were being built. I remember his story about a large hole that had to be had to be made in metal. He said that one company cut the hole manually while the next company had a big machine that punched it out. The badge has a number on the back of 8778 with an "A" above that.
