Here's the background and follow-up:
I was trying to decide between two B-stock instruments from a shop on Reverb. I asked what the issues were, and for one they sent me a picture of a small cloudy mark on the rosette. For the other they said it was a hard to photograph pinhead-sized dimple on the back. I purchased the latter without pics, and was very pleased with it when I got it. I still can't find the dimple.
The same shop recently had a sale on another B-stock instrument, of which they had several in stock. I asked if the quality was as good as last time. They said it was, that the blemishes were difficult to find, and that they'd pick out the best of their stock for me if I wanted one. The sale was ending so I quickly purchased and didn't think to ask for pictures this time. Not the wisest decision, but they'd sent me such an immaculate instrument the last time, I just assumed everything would be fine again.
The pictured chips were on the plastic binding of the lower bout. I got it yesterday and thought (with a little panic): does this count as a B-stock blemish?
The good news is, they don't seem to think so. They've offered to exchange it for another one, and this time I've asked for pictures.
