I have been very generously gifted a Grafton Alto from a stellar Tenorman from New York (whom would prefers to remain nameless if I know him, however I hope to publish some improvisational articles authored by him on SOTW soon). It was in need of some mechanical work which I have personally squared away, however, the Octave mechanism was damaged slightly, and the external spring(not the coil spring in the thumb key mechanism itself) is missing.
I can't seem to adjust it to function as intended without knowledge and diagrams of a working example.
Could/would someone with a Grafton, or a tech with knowledge of it's Octave mechanism please post some pictures or diagrams (no matter how rough) to assist me?
It would be very much appreciated.

), I have solved the problem myself. I discovered that the forked portion of the Octave arm that links the action of both octave key/pips was missing a section.
