This 1935 Gibson L-10 appears to be an early transitional example from when Gibson first moved the L-10 model from the 16-inch, parallel braced version of the original design to the 17-inch, X-braced "Advanced" model.  This guitar shows the early Advanced L-10 features of checkboard binding and paired triangle (bullet) fretboard inlays.  This was also the time at which the model began to have a sunburst finish, rather than the black of the 16-inch model.  This particular example shows an original tailpiece that is the same type used on the 16-inch version, consistent with the early example that it is.  Further confirming it as an early Advanced model is the FON consistent with a batch order in 1934 and a serial number consistent with early 1935.
 
This L-10, as mentioned before is X-braced and has the typical top carve of the era with a flattened center which those unfamiliiar with this era of Gibson often misconstrue as the top sinking.  These changes resulted in a guitar that has an overall more balanced tone, without such a distinct mid-range tone that the 16-inch guitars most typically had.  This guitar is a great example of that being very even from low to high.  It's been well played in over the years and has ample volume and headroom to a degree that is not always present.
 
The finish of this guitar has multiple areas that shows worn through lacquer which largely appear to have had what is probably some French polish applied over them.  There is a top crack at the bass side of the fretboard end and a center separation in the lower bout, both of which were glued long ago and are completely stable.  The back and sides are completely free of cracks.  The end of the fretboard and the immediately adjacent bass side have lost their binding.  The rest appears stable and these do not affect playing or stability at all.
 
The tuners show unusual wear, but appear completely original, being shortly-lived, clipped end Grover Sta-tites, only made in the 1930s.  The tailpiece and pickguard bracket appear original to the guitar, although the pickguard is a reproduction.  The bridge was replaced with modern made, compensated, rosewood piece that was fitted to the top beautifully and has room to adjust either up or down as the player prefers.  The neck was refretted and the guitar plays beautifully with a fairly wide nut width for the era and a fairly chunky neck that overall would be an especially great fit for those with larger hands.  There is ample room to add a floating pickup if the player desires.

The guitar comes with a vintage case that appears vintage correct.  The lower bout hinge has come loose and one latch is missing.  While the case will function for storage, I wouldn't recommend using it for transport without repairing these issues.
