The early ones are simply bolts in the side of the tank.  These are
the wands with reed switches (not relays) and floating magnet.  I had
some discussion with them before they started assembling about
providing proper strain relief for the component leads as well as
better sealing, and I believe these will be at least somewhat more
robust than the originals, especially as regards slight bending of the tube.
