Re: Question about 'hybrid' mandolins in old time
Remember that the introduction of the "long neck" F-5 didn't change the mandolin's scale length; the bridge just moved closer to the neck, more centered on the mandolin's body. Distance from nut to bridge varied little; Gibson standard, I believe, was 13 7/8 inches.
An oval-hole will of necessity have the bridge located further "south" than an f-hole, unless the soundhole's located up toward the "shoulders." How much further -- how this will affect scale length -- will depend on design.
