Simple, really: you've got a thing, you don't know what it is, and hopefully someone posts it.

I'll go first:

There's a bunch of these lead flasks[?] In the basement of the house my parents purchased.

So...what is it?
 
Okay kids, I’ll play.
Found this in the yard, and has been on my desk since.

About 3” long, copper by the patina?
Markings are:
#4 SOL
Pat 2215 (incomplete, maybe another 3-4 digits that can’t be made out)

Wtf I got here?

Looks like a weight that goes inside a window frame, makes the window easy up and down.
A little small and light for that application, plus I’ve edited- I think it’s copper, not brass.

I may have something based on a search of the 2,000+ patents that include digits 2215...
