Some of the weapons look like HEWJ sten-guns. The weaponry looks good but is unusable for historicals. Sadly, the glove-helmet is a fiction (as well as being incredibly uncomfortable, I suspect).
So, not for historical.
But they look fan-mazing and I want some for my Rhinoceros Air Pirates of the lost Planet Gron project. Two small curved armatures on the helmet and I have a convincing air pirate.
Bu the way, the standard international salute of all rhino air pirates is to place the thumb directly under the nose,with the index finger vertically exended and the remaining fingers closed. Then push the nose up with the thumb while screaming "Aaaarrrhhh-snort-bree" in a high-pitched tone. You'd be surprised at the reception.
