Not sure if the lighter colors of the applied pieces are copper and the rest is brass. Let me know what you think.
It's a beautiful piece. My research shows it's from World War I and is referred to as the French 75 field gun. Circa 1916 to 1917 further research showed 630 probably means the date L means a lot the MGM.
I'm pretty sure it means. The BX supposedly indicates the supplier of the metal.
I could be wrong on some of these things.
