I am planning to mess around with the 5th valve thumb paddle on my Willson.

I don't really love the stock thumb paddle, and the replacement that I had fabricated for it is okay, but a bit crude.

I'm curious if I can retrofit something else to work, perhaps like the new (or old) style Miraphone 5th valve levers.

Does anyone have a 5th valve thumb lever they would sell me? Just need the thumb paddle, I think...?

Thanks!
