Hmm... I don't think the stays are original.
Stayplate and insulators yes, but the cord looks wrong and has wooden adjusters instead of the metal type, the steel rings don't appear to be present, and I'd expect the cord to be whipped where it's tied off to the insulators.
Bag looks nice and clean, though.
Still a bargain at the current price, of course, and it may be a genuine "war economy" variation of the stay assembly.
