Found in a Creek

[eagles9259]

I have no idea what this is. It is approximately 5" tall and 5" across. I found it with my metal detector, a couple inches down in a very small creek. I have found things from the CW as well as things from the 50s and 60s in this area. The part that sticks up is (or was) threaded, making it some sort of bolt that you would tighten down. Any help is appreciated.
Thanks,
Matt

It looks like the bottom part that the sink strainer sits in? plumbing related.

Now that you mention it, it does kind of look like that. But it's much too large to be a sink strainer and much heavier duty.

It looks like part of a strainer from a grease pit in a butcher shop

It looks like a rusted out lawn sprinkler.

I have seen dampers on wood stoves with that style construction.

Reminds me of the device that is used in a toilet (john, commode, crapper, etc) where the back tank and the toilet meet, used to hold the tank to the toilet, circa 1950 to 1960. Clean water flows thru the opening in the ring; the threaded rod (with wing nut) holds the tank onto the base, and the black rubber donut gasket (missing) keeps the whole thing leak-tight. - JHinPA

Possibly an old radiator cap from a tractor or other large machinery. I couldn't find the exact thing I was looking for but they were cast iron and the screw thing tightened it up by pulling up against flanges on the pipe. Picture might stir somebody's memory.

It looks like the outlet in an urinal, calcium and all

My first inclination was a radiator cap of some sort also. Monty
