Knew i'd commented on this type of instrument recently, but it was on a similar one featured on tuba tuesday in the simonette collection.
They are worth playing, and the right size for a set of folk that don't really have any other BBb options.
I was going to say that it is local pick up on Long Island. Just make sure you are awake if you plan to drive through The City. Oh, and don't be surprised by excessive bridge tolls.
i was sent an offer for this horn however the owner never got back to me on getting shipping arranged.
i have played one that was for sale locally about ten years ago, the back pressure made the instrument unusable to me.
i still own one in parts that i planned to restore but after moving twice the valve section was lost .
