Excellent British tonearm, this inspired the similar Audio Origami PU-7 which retails for 1700 uk pounds (or about $2700). In nice shape with box/manual etc., see pictures.
The Syrinx PU3 Ipsissima was developed from the earlier PU2 and had improved levels of engineering and finish.
The tonearm featured a cigar shaped arm tube with integral headshell in a massive gimbal bearing assembly.
The arm tube of the PU3 can be rotated in it's mount for cartridge azimuth adjustment.
A threaded counterweight is employed which can be locked in position.
Anti-skate is of the thread and falling weight type.
