Pittsburgh Steelers buckle measuring appro. 3" x 2.5". Polished brass buckle with epoxy Steelers design helmet affixed. Fits standard belts up to 2" wide. These were issued by the former Raintree Buckle Company back in the late 1970's.
It is important to note that these are classified as dress buckles, not work buckles. As such, they can easily scratch. I still have the original cardboard box with insert but the plastic cover is gone. This is the last one I have.
