Spacers for French, Belgian or Russian Helmets. A set of four spacers, two long, two short. Your choice of punched or unpunched. Because of the great variations in the hanger tabs on different Adrian helmets, I would recommend the unpunched spacers. You can take a flat tipped screwdrive or small chisel and punch your own slots in them to match the liner mounting tabs on your shell. Otherwise, I just take the "average" and stamp oversize slots in these. Most of the time they work...!
