Valve Buttons (Caps) for an 1890s Conn Helicon
Posted: Fri Mar 06, 2020 12:25 pm
Hi. I am looking for valve button / caps that will fit my Conn 1890s Eb helicon. I have two of the originals, complete with faded silver plating, but I am missing one. I have a substitute that fits from a screw hole size point of view, but the metal on the bottom of the button clashes with the raised metal on the top of the valve cap, and does not allow the valve to completely close.
Here is a photo of the helicon, and photos of one of my valve cap buttons next to a modern Conn one. Mine are smaller in diameter, and have a smaller screw size.
Does anyone have anything they would like to part with? Preferably three so that they would be all matched, but if someone has one I would be interested in buying it.
Thanks.
