Circa 1939 Bacon and Day Senorita S-1 made by Regal in Chicago in excellent condition.  As far as we can tell this is the sole surviving example of this model.  It is X braced, non-scalloped and laid out like a Martin 00 size.  Solid spruce top   The body shape is like an L-00 with a slightly narrower lower bout at 14" across.  The scale lenght is 25" and nut width is 1 13/16", string spacing is 2 5/32".  It has a previous neck reset with a good angle and centering as well as a refret.  We made a new saddle and straightened the neck and it plays beautifully there is a steel reinforcement in the neck as well.  The wide yet not too deep neck is comfortable with plenty of space for finger-style playing. The sound is dry and woody.  It has its own voice that is not Martin or Gibson.  A rare and wonderful guitar in excellent condition.  Includes recent hard shell case.
