Apologies for the cross posting but I've had no replies on the Audio Origami forum.

I am unpacking a rewired Syrinx PU3 that I bought secondhand but I'm missing a grub screw from the arm lift pillar. Does anyone know what size it is, it looks like a 2M hex. The plastic curved arm lift has also come off the lift pillar piston. It looks like it was glued - can anyone confirm this how it is attached. Thanks a million.
