I was told that there are over Five Thousand Police Forces in America. Many are very local. This Badge is for the City of Baltimore, which is obviously one of the bigger ones

A very attractive badge......It measures some 124 X 105 mm in a Shield shape.
"Quartermaster's Comment":- I think that we have here the Baltimore City Coat of Arms......with a picture of the Main Statue in the City Centre super-imposed thereon.
A very pretty flash.
