Ihave a u.s. collar disk with the letters PR stamped with the state of NY seal in the center. Any ideas as to what the PR stands for? Pioneer Regiment, Photo Reporter, Public Relations? Yes it's a screwback.
Thanks. I'll keep trying myself. Maybe the NYC Police museum can help or perhaps the Police Reserve which I found a web site for and they state they have been around for 85 yrs. I e-mailed them both but still waiting for a response.(nycpra.org)
