near toilet floor constantly wet

I have always used a 1/4" drill bit to remove the lead. If a length of pipe was still in the hub then a 16" long bell hanger bit was used.

Then with most of the lead drilled, a hook was used to dig out the remains.

Then the pipe stub could be removed and the oakum drilled or hooked out.

when the lead was packed in, it should be slightly lower than the rim of the hub, like the photo shows. but in my photo, why is the rim not visible?

Looks like a lot of rust covering the rim.

do some digging and scraping and see what you find. you can't make it worse.

there is some sort of caulk substance that has been sold for years for use in place of the lead, it could be that too or the lead could have been poured flush and not packed

could you show a picture of the bell hanger bit and the hook?

a bell hanger's bit is just a long twist drill, it is maybe 18" long or so. the hook is just a big pick or hook with a screwdriver handle on it. they sell them for releasing radiator hoses but there probably are other ones out there too.

This electrical box houses two spices. Some insulation jacket already shed off exposing the wires. I measured the voltage between the exposed wires and got 0, the differential between the ground and either wire is 0, so this box was decommissioned already.

that type of wire is pre wwii

So back to the question, can the electrical box be wired to a buss bar for the grounding of the whole house? The existing circuits in the house do not have a grounding wire. It was the then current code.

The boxes and the jacket of the bx and the conduit are the equipment grounding conductor in that system. If it is wired with that method all the way back to the panelboard or with another wiring method with a ground then you bond the ground terminal of the device to the box.

that is a branch circuit, that is not part of the grounding electrode system for the service.
