We have named this guitar the 'mystery L7' This guitar has a FON from 1933, and a gibson finish from, well, I don't know, but certainly later than 1933. Why does it have dots rather than window frames which would normally be found during that period. Is it early enough that it could be a prototype with dots? That could just be gibson being gibson, with all of the oddities that show up, special ordered by 'Willard', whos name appears on the truss rod? or it could have an answer that has yet to be revealed. Another oddity is that the label, which is original, is in the upper middle of the back of the guitar, as if it were supposed to be an oval hole model rather than an F hole model. The tailpiece is a later one, tuners correct. There are no signs of any repairs ever having been done, it is in more or less new condition, the neck has the appropriate 'V' contour for the period. I'm an avid archtop guy, and know a lot about these, and I've showed it and talked to other knowledgeable folks to get opinions, and there just isn't a lot that makes sense when looking at all the different aberrations. Could it have been sitting around and finished years later? Was it sent back for a refin? What about the oddly placed label? Anyhow, it will take someone wiser than me to come to a reasoned explanation. Clearly everything done to it is Gibson from some period or other. In any case, it is a fine, deep and dark sounding and lovely 16" gibson arcthtop, a true time capsule, that much I can say with assurance!
