Luthiers, Dealers and Orchestra Players: Have any of you seen or plays a Bass by Oreste Martini? Mantova-Italy, First half of the 20th Century. Dates from around 1918 to 1957 or so. I am looking into a Bass by him but it's in Europe and can't play it before buying it. Curious as the the tone or sound of this makers Basses. Have seen two in pictures. A 1921 flatback and this one I'm looking at from 1918. Beautiful Violin form but can't hear the pictures!
