This is Grand Auditorium, Pre WWII resonator guitar with body made by Regal/Wards. It is a "jumbo" shaped body with 16" wide lower bout with an arched back. The Wards sticker is visible through one of the screens as is the wooden sound well. The neck joins the body at the 13th fret. It was converted to 8 string but has been restored to 6 (replacement headstock veneer is a perfect match to the original). Round neck but set up for slide. Same model as used by Shot Jackson.
