Vintage Chanel Bags : Did they use FAKE LEATHER?

Is this a real Chanel bag? The exterior leather was good, but what we found on the inside made me doubt the authenticity of the bag (despite verification by Entrupy). This bag was sent to us by The Luxury Leather Guys. At first glance, the inside material looked like real leather- but the acetone application revealed it was fake leather. I do not know enough about Chanel's earlier manufacturing to conclude if the bag is fake or if using fake leather was an actual business practice. At Chanel's level, it wouldn't be difficult to use real leather on the inside, and that's why the use of fake leather there set off concern for the bag's authenticity and the methods used by authenticating systems. Overall, the bag was pretty well made. Exterior leather was good for it's age, but it could have used better care and condition by the previous owner (some cracking). The fake leather interior however, is not what I would expect to find in a luxury leather bag.
