Look similar to the disks you get in larger para illumination mortars.

Ive attatched an image of the M301 and highlighted the part im talking about as its the only part i can think of

They look like the discharge plates from the base of a Smith gun projectile but I can't imagine what they were doing in the US ! Just a thought......!

Not in the USA siegfreid ,,a couple of old ranges/training areas here in the UK that were also used by the USA the majority of finds have been USA in origin

Allan. Whoops , misread the post ! Old age & an addled brain catching up . I still think they could be from a Smith gun proj.

Would be interesting to find out what these are as I often come across plastic versions of them.
