I can tell, the 2 little slots will be the tricky part to do correctly...patience grasshopper

Thank you to both of you,
I tried Bach nuts on the Conn and they are too small...I suspect size 6 something.
I like tinkering with stuff and have square 1/8' brass stock. I'll see if I'm patient enough to make a few guide bars from that..but ABS sounds easier to work with, worth looking into.
Thank's again

Sorry, no prize, but wondering if anybody makes late 40's Olds trumpet valve guide bars ( for double slot piston barrels)
Also, does anyone know the rod thread size used on mid 60's Conn Constellations.
Thank you for all your help

Hi, Looking for 3 finger buttons and at least 1 top and 1 bottom cap in brass,( could buy sets if needed) for a mid 60's King Super 20 Bb.
Looking for used original parts, no repro parts please

Thank you for your inputs.
Barliman: I use a Giardinelli New York 6sv screw rim, my Bach is a '74 Stradivarius Lt trumpet, not a cornet ...The Sovereign is a Studio model trumpet , not a B&H sovereign cornet.

Ivan: thank you for your usual insight into trumpeter's OCD

Hi, I'm contemplating replacing the receiver on my Sovereign Studio because of the following; I have read that mouthpieces goes into those a little further. My mp sits 3/16" further in than let's say my Bach strad also. In any case the main slide sits about 5/8" + + out to be in tune. Is this cause to change it out ? if so, where would I start looking for a replacement receiver? gap on both horns look to be close with mp inserted...am I over complicating things?
