Oh my that is certainly interesting, I would have never guessed based on the bag itself to be old as it doesn't seem like its aged design wise for it to be "vintage". I even compared the hardware of it to the proper Burberry ones and I would never have guessed at all without your knowledge.
So far with the one I have quality wise is actually good even though the previous owner used it as a workhorse. Maybe I got lucky, lol. I purchased it at a reasonable price which reflects of what you said about this bag's original origin anyway so its all good.
I'm so with you on the "perfume bags", its frustrating to see it being sold at absurd prices.
Again thanks for authenticating and sharing your wisdom, I learn something new everyday.
