Hi, i'm from Italy and this is my first vintage guitar I purchased 15 years ago. I think the guitar had some issue so I need your help to date and value correctly 'cause i would like to sell it. I can see that: 1) back neck had a refinish 2) maybe guitar had a factory bigsby replaced with a stop tail 3) fretboard refretted Someone sees other strange things or changes. I purchased as 1965 and you can see serial from pics. However serial is 512485. Thank a lot for your precious help. Cheers from Italy!!
