I am really getting confused here and appreciate any help. I bought this Les Paul back in the mid 1990's. The guy that I bought it from said it was a custom shop I don't guess I even asked about the year. I see that most people don't put the whole number on the web so I guess I'll follow suite. The serial number looks like this: 5 44XX It is "inked" on the headstock. Looking at this site, it looks like a 1950 something. Vintage Guitars Info - Gibson collecting vintage gibson guitars Here is a picture off that site that looks like mine. If it were a 50 something, it would have to have been stored in a case all these years. I'm sure there is some type of exception to these numbers. Thanks for any help.
