Today I learned that John Packer Instruments idiot-proofed the JP377 tuba valves by making piston #2 slightly larger than #1 and #3.
(It does not matter if 1 and 3 get swapped around because the port locations are identical, but 2 is different. #4 is shorter than the others, so it only has one place it can go.)
