Picked this project up locally today. It was advertised as a '50's-60's J-45, but it was my understanding that the J-45 was offered in sunburst finish. My initial thought was that it was actually a late 40's-50's J-50, as it appeared to be a natural finish from the images posted. Now that I have it in hand, it's hard to determine exactly whats going on. My best guess is that the guitar has been refinished, though I don't know that for certain. The prior owner seemed to have little to no information on the guitar to begin with. Any assistance is appreciated. Images are posted below:
