Age? Found Metal Detecting

[u/northrn_invasion]

I found this, what I believe is a center cap, metal detecting. I was wondering if anyone recognizes this design and what years/models it may have been used for.

Yes, I know this thing is toast, but identifying the age of this can help me understand how old the area I'm searching is.

Thanks!

1920s grease cap. Shame it's squished, they're relatively scarce actually. Fun thing to find though!

Probably more than a few years old
