Mid Twenties Paramount Model R Mandolin Banjo
I guess maybe they might have called it a Mandolin Banjo Harp since their wooden topped tenor banjos were called tenor harps and their five string wooden topped banjo was called a banjo harp.
But here she is in all her glory and she sounds pretty darn good.
"Leader" style inlays and rosewood resonator.
Lovely marquetry and binding throughout.
And .. eight! Page "E" tuning pegs above the classic volute.
