Guys,
Sorry this seems like offtopic to this forum, but i really need the experts to help me identifying this item. Im collecting 1/6 military figures, i ve been having this item for sometime now, but i dont know what it is, ive been researching and the item looks like a oxygen hose regulator. Perhaps anyone here has some references pictures of the real thing and how do you connect it to the oxygen mask hose, i have attached the link of the pictures below (the item is the one in red circle), any help would be greatly appreciated
