Our friend Tom Marinus finds in 2022 with detector bullet
shells in the two positions where the Western machine guns were located
"Gi ctor la testa" (Get down, bastard! ). EXCELLENT FIND!!
Those would be the two separate rivets from two separate machine guns used in the Sergio Leone Western, "Duck, You Sucker!". One machine was used by Rod Stieger, the other was used by James Coburn. Those rivets were on those guns. And those guns don't work without them.
