Hey Margo,

Is that the original neck and tuners? I guess it must be if the part going through the body has the logo stamped on it. So, yours is already a five string. I'll bet it sounds dandy too.

I can't quite see any of the detail on the headstock in the photos you've provided. The resonator's back looks exactly like mine and mine has that same tone ring. Mine also has the stamp on the part of the neck that goes through the body. My serial number is there too. The body looks virtually the same as my four string.

A detailed image of the headstock (perhaps featuring the tuners) and tailpiece would be helpful for your sale, as these are items that many get replaced over the years. Collectors like all that original detail intact.
