If they just chopped the lunette ring off and welded a ball hitch reciever on the shaft then your in luck. Midwestmilitary.net carries in house reproduction lunette assemblies. They aren't cheap, $185.00. Omix Ada also carries reproduction pieces made by MD Juan but, they are for the MB trailer (WWII trailer) but, I am unsure if those parts will work on the M416 trailer. For cheaper solutions check Ebay and G503 trailer forum. If the butchered your tounge and landing leg casting assembly you'll have to watch ebay and forums such as G503 to find a good used one.
