Wtb: Conn valve caps

Post by York-aholic »

Hello. I’ve got a Conn 28k Eb sousaphone that is missing some valve caps. I’m on the lookout for 2 top caps and two bottom caps. I suspect some of the other Conns would have similar caps. Pictures and dimensions to follow. If you have anything, please let me know.

Top cap, note knurling on two spots

Bottom caps have same ID and threads as top caps, just plain rotten, casings and other caps are fine

Some old Yorks, Martins, and perhaps a King rotary valved CC

I’ll check my parts. Pretty sure…

They may be silver?
