All Hawaiian solid KOA with 6- 3/4 inch bridge. "The factory guitars from 1922-1926 are lightly braced and have a bridge that is 6-3/4 inches from point to point.
The factory guitars from 1927-1937 are heavily braced and have bridges that are 5-1/2 inches point to point.
The shorter bridges are a spotting feature for me. The 1922-1926 factory guitars sound better than the 1927-1937 because they vibrate more, giving that long sustain and ethereal Weissenborn sound".
"Jerry Douglas plays a Weissenborn Style 1, and tunes it to open D (D A D F# A D) with D Addario phosphor bronze strings: 14-16-26-036-044-060"...Incl TT hardcase..
