I am stumped on this one. Could this be a huge button.

Is the back lead?

 

[vayank54]

looks like a tin back horse rosette with the hooks rusted off

 

[PBK]

I'd guess rosette, too; and if that's lead fill on the back, as suggested by Creskol, that would just about cinch the ID.

 

[Garabaldi]

Don't think its led, the material flakes off.

 

[Garabaldi]

I looked up what a horse rosette is. Were they a standard item for horses or a prize with ribbon attached for winning an event?

 

[dugit]

Looks like the plate off the burner of a gas stove. 50's maybe

I have found an iron patch in the area, with a half horseshoe.

I think your's went on the harness and was a decoration more than anything else. One with a ribbon could look like that but I don't think it would have a brass face.

Thaks vayank, i'm green checkin it baby.

freeze out plug for an old engine?

and a couple more:

Are they threaded? The one I have does not have threads on on. Those images sure look a lot like mine. Seems more plausable than the horse piece.

 

[vayank54]

I've never seen a flat freeze plug. All the metal ones I've seen are cupped. To be honest I've mainly worked on older cars and don't know much about the newer ones so I'm not sure what the newer ones look like but can't picture them being flat as they need something, like sides, to guide them into the hole plus when you press them in the sides expand to help hold & seal them. In the pic it looks like your piece has a brass front and tin back. I have dug quite a few rosettes that look like what you have pictured. I'm not saying it's not a freezeplug but I truely don't think it is so don't throw your piece away until you find out for sure.
Here's a couple pics of one I had handy. It is a bit different but has a brass face and tin back and still has a bit of the wire hook left.

i have neve seen a threaded freeze out plug.

they are slightly concave on one side and convex on the other.

some have a lip around the outer edge, some dont, and some

after laying in the dirt for years, look just like your picture.

next time you go out, swing by a garage with an older

"shade tree mechanic or grease monkey"

and ask his opinion. a younger one probably wouldn't know.

 

[Bigcypresshunter]

As a middle aged shade tree mechanic that only worked on my own cars, I thought the large sized freeze plugs were cupped with lips too but Dozer posted pics of freeze plugs without the lip, so they do exist. I guess used on modern cars. They look like large carburetor plugs.
I have never seen a threaded one either.

However the freeze plugs I have seen are usually rusted thin in the center and often damaged from removal. But the clincher is that freeze plugs are either brass or steel, not both. As Yank pointed out this piece appears brass on one side and rusted on the other. So I think horse rosette is the correct ID. (if it is brass on one side)

ADDED: I may also add that I never saw one over 2-1/2 inch dia and this appears larger. What is the diameter, G?

about any diesel engine in a large truck or heavy equipment has larger ones.

although........ a round rusted piece of steel of this size could be just about anything under the sun.


i'm runnin out of ideas.

next?

 

[Garabaldi]

It is about 2 1/8 inches in diameter.
