This Swiss case by Altdorf has a fuze I have not seen before. It has traces of yellow paint so maybe HE or HEI ? The fuze has a pin with a hole in it and I ask if it an Oerlikon patent and any details.
Is it a normal RH thread as it looks inerted but is too tight to unscrew unless I soak it. Was it made for Japan before they made ammo for this cannon?
