I'm looking for a replacement tuning crook for a Conn (1950) 4H. The part appears identical to the late (brass bell) 18H. So either should work. Conn-Selmer no longer sells the part. I only need the crook (bent tube) not the whole assembly. The 22H / 23H part is too narrow.

The 4H:

Spacing between tubes on the inside of the curve is 3.78"

Outside spacing is 5.16"

Outside diameter of large end: 0.75"

Outside diameter of small end: 0.63"

Also could someone check if Allied has it? Their catalog is locked unless you have an account, i.e. can prove you are a business not a hobbyist.

Mouthpiece express has them for $35 - to fit the older Conn Director models - ex: 18H etc. Should someone else be on this quest....
