TubeNet

To anyone out there in tubenet land. I am looking for older 6/4 Nirschl York tubas to buy. I have two that I am happy with but would like to have a third. I am interested in the older instruments in particular (1995-1999) but am also interested in any vintage Nirschl 6/4 tubas. Please note that I am not interested in any combo horns, i.e. york bell and Nirschl branches or any other such instruments. Any leads or direct contacts would be welcome. Thank you for any help.

Sincerely,

For the uninitiated out here, what makes the previous generation superior?

I did not say that they were better only that I am interested in the older vintage horns. Thanks.
