Re: Gibson ES 150 on ebay... wow...
A friend of mine has an all-original mid-Sixties ES-125CD. Many of the woodworking details and shrinkage artefacts on his guitar resemble those on the eBay listing.
Looking at the eBay photographs, the neck profile looks correct for a Sixties taper. The fingerboard wear is either superbly relic-ed or it is the real thing. The headstock looks terrible. Not only has it been badly painted, it appears to have been brutally sanded first. (The "moustache" end shape is well ****ed.)
IMO, the eBay vendor is telling it like it is. P R O J E C T. Only you can decide whether the financial outlay of a full restoration is justified.
Getting back to my friend's ES-125CD, it made superb mildly overdriven jazzy Blues sounds - especially on the neck position P90. (One P90 would be enough!) Just to put things into perspective, my friend paid the equivalent of over $2500 for his guitar.
