It looks like the back door, which opens with the original latch, was painted at one time and that paint has worn as shown. The inside bottom is a little rough; I have seen one of these cases with a green felt covering on that section. There are a few scratches to the glass, the etching has to be seen in the right light to be perfectly visible (I have seen one example with a mirror on 1/2 of the inside of the back door and this may make some difference), and some wear to the wood in spots.
