Thanks so much for the Harry Virtz link. It makes sense that the tonearms were made in sections. If you look closely at the picture I uploaded you will notice another join at the other end of the tonearm. I've seen two tonearms with the same two joins. Why the join so close to the J-tube?. Also, there may well be but I can't see any evidence of a seam running along the tubing.

It seems possible that the straight sections of Expert tonearms were made up of lengths of seamless pipe using conical tube-expanders. This might have necessitated more than one size and therefore more than one joint ? I have some of such tooling here. EMG did use brass castings for parts of their tonearms which were made in sections and then joined---usually towards the bearing end.
