    Hello:

    With help from a friend, here are some photos of AH. Since I last wrote, I've found on-line more pictures of these devices, but none with a basin having a threaded connection in the corner. The tip of the cone/jug is missing, and the small threaded connection on the interior tip is partially broken off. There is a fine hole in the broken tip/threaded piece.

    I now believe the missing tip was a transition piece that allowed the jug of fluid to be directly threaded to the basin. The basin has a 3/8 inch bolt thread. The top of the jug where you see the plug is a 7/8 inch bolt thread.

    I suspect the pouring process went something like this: 1. The jug was removed from the carrying box and the missing transition piece was screwed into the basin. 2. Plug removed. 3 . With the basin inverted , the basin was screwed onto the transition piece with jug. 4. Then the entire unit was inverted with the Hg flowing into the basin. After CN work completed, the HG was poured back into the jug. Note how the cone can be inverted so it acts as a funnel for the fluid going into the jug. The corner of the basin has the pouring spout. Maybe?? Pretty simple and neat!?

    A friend has access to a machine shop and I'll have a brass transition piece machined. I would love to know how the original top piece and any other components looked. I've given up looking online and maybe I'll contact the RPI library in Troy NY. Maybe they have some old Gurley catalogs.

    Has anyone ever used something like this? Thoughts?

    Bruce
