G'day all from the land of OZ . Being a new member and my first post please excuse any mistakes as I am still finding my way around . I am trying to ID an unknown ( to me ) 37mm projectile . It has a OL of 142mm with no body marking but the base plug is marked with MBT I and a diamond with a line through the center and 4U above the line and EF below the line . The closest thing I can see to it is a US 37mm Hotchkiss sub-caliber but this is more pointed in the profile and the band is not the same . Any ideas ?
