🔎 UNIDENTIFIED Flange Spacer - Antique Auto?

[Warrington]

A little background. I invited several detectorists to explore area around my colonial house. So far, except for a few wheat pennies, they have found about 30 pounds of iron. Largely farming relics. About 6" down, they found this. It may be important to note the house has never had steam heat. The shape immediately suggests to me some connection with the thermostat in an auto's cooling system. I think it important to note that it has a "bleed" allowing fluid to flow out of it, perhaps to a pressure or temperature gauge. It has a part number, but it is now illegible. Anyone recognize it?

Looks like a gasket/spacer that goes between a carburetor and intake manifold. Probably off a tractor or other piece of industrial equipment.

True, I hadn't thought of a single barrel carburetor. Might have been used to pull a vacuum for something.

Lots of early autos had vacuum windshield wipers. that would tie in to a intake manifold spacer and drawing a vacuum1

Whatever it is, it looks pretty modern to me, 1960-1979?

Maybe it fit on an engine thermostat housing to connect a temperature gauge. I'm with Goldie. It doesn't look that old to me. Mid to late 20th C.

Probably looks newer than it should because I glass beaded it. Since it was found about 6" down, I expect older.

Last summer my son lost a ring at a family reunion. I went back in March with my detector and found it - already an inch under the soil. Soil density and weather conditions can play a role in the depth of relics in top soil.
