York tuba and Sousaphone receiver wanted

[Tim Jackson]

I know it's more fun to talk about the old outdated 186 5U CC or my antique good for nothing York BBb so here's a nice picture of the York and if you can help........
My Conn 36K Sousaphone has a missing receiver and the lead pipe is crushed in but may be repairable. I was thinking it might be just a cheap to buy a used "bone yard" pipe and receiver maybe one of you repair guys has laying around. Also need one finger button. 70s-80s vintage Conn 36K fiberglass sousaphone. Any used parts or old new stock - receiver, lead pipe, bell screws, finger button. any finish and worn old but usable welcome. Can trade money or rare tuba music.
Thanks in advance regarding the whereabouts of these items.
