The slightly arched back is solid oak, as are the sides. There is an inlaid center strip, which is not the same pattern as the rosette. The single piece neck is mahogany. The peg head sports a Royal logo decal. The tuners shown here are modern replacements. The guitar came with a mismatched set of period tuners. One side appeared to have been original, the other side was made up of spare parts. The original tuners were solid brass, thus dating this instrument probably prior to 1920. The previous owner said he thought the guitar was made by Lyon & Healy, and I concur. I have been unable to find out any information on a "Royal" guitar brand from the period, but assume it was one of the many house brands manufactured by L&H.
