Brass threaded piece

[Underwonder]

Hi,
This seems to be a heavy brass item shaped like a lilstick top with a threaded bottom and harchmark design around the edge. Any ideas what this might be? Thanks!

Finial for the top of a lamp, to hold on the lampshade?

Looks like an old style valve stem cover.

I agree with creskol.

Reminds me of the model t valve stem cover, yours is a little different though...

Thank you, creskol, and everyone for your replies. That sure is what it looks like! I’m not sure why it had a big hole in it. Maybe it blew off. You were so quick to respond! Thank you. Sorry my return reply was so delayed.
