Hi guys - first thread on this forum - I have an old stock ES-175. When I got the guitar in 1985, I wrote (pre-net!) Gibson to ask the year - their response was that due to fire which destroyed old records, it was either of the 2 years mentioned ('63 or '67). They said I could break the solder-seal on the pups and there would be a date or identifying # there... I've had no reason to do this and am reluctant to 'un-do' something original. Does anyone know any way to id the year from visual clues? Will it make a difference in the sale price, should I decide to sell it? It's in very nice shape - not mint, but close; rosewood 'board and saddle/bridge, great fast neck...
