Hey, I'm Not Sure Where to Post This so I'll Do Post It Here. My Opa Who Used to Play Tuba Recently Passed Away and My Oma Could Really Use Some Money So Shes Asked Me to Help Her Sell Them. Neither Her or I Know Very Much About Tubas So I Was Hoping I Could Write This Post and Get Any Information Anyone Might Know About Them, Thanks.
