Maybe not the right place but I thought with all the interest in old NYPD and other old police revolvers I might share this. It belonged to my father, carried it with a Colt Agent. Its an ammo carrier that was made for a historic gun shop. The belt slot is only 1", that dates it back to late 30's early 40's by suit attire. John Jovino Gun Shop or the John Jovino Company was a firearms dealer and factory located at 183 Grand Street, in Little Italy, a neighborhood of the New York City borough of Manhattan. It was the oldest gun retailer in New York City and said to be the oldest gun shop in the United States. The store closed as a result of the financial hardships from the COVID-19 pandemic.
