Tone-Gard for Mandolin - vintage gard

From the ToneGard website;

 VintageGards (6-ray design) are for mandolins that are 10-3/16 inches across the back, such as old round hole Gibsons, Weber Absarokas, some of the other Webers (including some F models) some Hillburns, Newsons, etc. If you have one of these instruments, please get the Vintage, and dont try to bend out the arms of a Sunrise or Deco to force a fit. It really wont work.
