I'm a newbie to Gibson acoustics. But just purchased this Gibson guitar off of craigslist for $1,650. It's an original lefty. I own a lot of Gibson electrics, but never owned a Gibson acoustic. There is no paper label inside the guitar to know what model it is or any way to know what year it is ? I was told it's a 1969. Serial number is 850257. Any expert out there that can help me out? Thanks.
