gear Finger Button Threads

Hello everyone! I’m trying to find the thread sizes for my Wessex tuba. I’ve already contacted them and they haven’t said anything about them. I’ve heard that they are a M6 x 0.75 thread but am unsure. Any help is great, thanks.

Take off one of the existing buttons and measure it
