🔎 UNIDENTIFIED Some type of cap?

[Bucket Lister]

I try to record what I can about finds that are/look interesting. I don't bother recording the junk anymore--I just pull it out and dump it in the recycle bin on the way home.

This one stumped me. I guess I'd call it "interesting junk" and leave it up to my better half whether to keep it or not.
What am I saying? I KNOW what she's going to say...! 🤣

2½" diameter, ½" deep rim, non-magnetic, may be tin or zinc--IDK. Rang up in the high 80s.

Looks like an aluminum lid to me. I just found one similar that says Lyon's on the top. Turns out it's from a Dr. Lyon's tooth power can. About 100 years old give or take a bit.

THX. Unfortunately, there are no markings or writing on it. The center is slightly domed.

So is mine.....slightly. Your's may have had something on it, but, got squashed. Here's mine that might look like your too if it got flattened. Similar anyway....sure did sing out loud!

Never seen a radiator cap made of aluminum.

Might be a hubcap from a kids wagon.

Like said maybe a hubcap/axle cover of a toy or part of an old battery.

Kids wagons have hubcaps? Hold da phone...

OK, just went out to the garage; I still have my wagon from 65 years ago... Yup, it's got hubcaps, but they're steel and much more substantial.

Like said maybe a hubcap/axle cover of a toy or part of an old battery.

Part of a toy was one of the first things I thought of, but something to do with a battery or lantern...

I just scraped some more crud off of it, and there appears to be something like a rosette design around the dome. I also found there's a pin hole in the very center. Now I'm thinking along the lines of gas cap, except the rim isn't threaded.

Perhaps early gas/kerosene cans didn't have screw-on tops? Anything else have a vent like that?
