This is a Waffen-SS cap-skull. it is the so called tropical version (golden, yellowish coloured).
It is a bevo pattern and is in total mint unused condition, impossible to upgrade!
If you want only one, then this is it. These tropical ones are not as rare as other SS skulls, but they are already not as easy to find anymore as they used to be. It’s still a nice and affordable original item for a great price!
