✅ SOLVED large iron and brass object

[divedigger]

found this thing and have no idea what it may be. It is 8 1/2" in diameter, very heavy iron with a thick brass band. Topside has a large thread that looks like it locks in place when turned. Reminds me of a breech or a bolt. I don't know. Any help is greatly appreciated.

Looks like a turn table for a grist mill

Don't know what it is, but it's certainly the nicest one I've ever seen posted here.

It looks like a foot for a large jack or ram of some kind. The way the backside is cast it would let the cylinder, or jack pivot a little? Tony

Vintage in-ground valve box cover?

Part to a large gate valve

I'm with vhs07. The brass seal had me looking at large gate vales and I came across this item called a tap or wet connection used in a municipal water system. This example is a 6 inch tap connection.
