Thanks, chowlover2! The seller said they were ALL vintage (50's) Chanel. The first one is very dark navy jersey fabric and the inside matches my lambskin version, except the turnlock and the chain. I believe this is a mademoiselle lock. Every corner was shredded, so I did some really careful handstitching. This was the "before" pic. Still needs a thorough cleaning.
There are no stickers...I believe they are way too old for that.
Here are 3 pics of the navy jersey, showing the inside flap, logo stitching and back pocket. There is a very worn, imprint that once said Chanel.
The stitched logo on the other 2 is different, yet similar, and there is no Chanel marking whatsoever....but the chains are identical to the first one...very, very heavy. The black suede is lined in deep red smooth leather, the brown jersey is lined in burgundy/brown faille.
I will likely pursue authentication as you suggested...inquiring minds need to know
