Hat pin maybe

[sscindercoop]

Found this in a local park today. At first i thought it was a pin until i realized the back has a bolt mounted on it. Maybe it went on a hat ? Also would like to find out the age. Thanks in advance for the help.

Collar brass, I think WW2-present vintage.

Pre WW2 post and screw collar disc. Stopped being used mid war or until stocks ran out. Current brass is clutch back.
