It was a while back, but best I remember...my friend said he bought it in the late 80's and it was a limited production (only 20 or 25) custom shop reissue. That is why the low serial number. I don't remember which reissue it was. The handwritten part on the label definitely says "serial number 0015 and model number ES-335-DOT") The D could either be a 0 or a D, but makes more sense to be a D. I still haven't heard back from Gibson since calling them and then sending them pictures.
