WANTED Aeolian Vocation golden revolver tonearm

[Inigo]

I'm in desperate need of a new tonearm like this one

I really need only the central part of the tonearm, the one that starts in a spherical joint and is straight, curving at the end in an elbow with set screw, to receive the soundbox Z elbow. The back bracket also would be great to have (mine is also broken).
I would also take a complete tonearm, if it's available.
