Wow! I have one just like it, dry wood, no oil problem, case color is 100% in the area and there is not even a light scratch on the metal to indicate any bruise from handling? The only clue I can add is the finish was wrinkled from some unknown cause. I refinished the wood and the results were great except at the "burns". I then tried to glass the "burn marks" and the results were not great.
wthigo?
