Vintage Blue Glass Chevy Grill Emblem

I believe this Blue Glass Chevy Emblem would fit over the center bend of an older Chevy model vehicle. It's made of white metal and blue glass. The second picture shows a crack in the center of the glass. The glass is still tight, it won't come out cause of the crack. It's still a good old neat piece. It's 7 3/4" long.
