Hi Ted; I've never seen anything quite like that from WW1, are they Allied or German? I'm assuming it's defence against tanks, but that's because I can't for the life of me think of anything else at the moment. Either way another cracking find, thanks for your continued efforts.

Pete.

I do believe they were German, Pete.  And yes, they were anti-tank defenses!

Appreciated matey, you learn something new every day.
