Vintage WEMP 1250 AM Radio Station Brass Belt Buckle Centelfugal Casting Co WI

Just found this WEMP brass (sure looks like brass, but I am no expert) belt buckle in a drawer as we prepare to move to warmer and less taxed climes. WEMP was a Milwaukee Wisconsin AM radio station back in the day. About 3 3/4" x 2" rectangular and probably was worn back in 1970's. In nice vintage condition. HOWEVER, there are some small marks by the "E" (see photos) and some small marks on the back of the buckle. Made in the USA by Centelfugal Casting Co. This is stamped on the back. Please look at all the photos and ask any questions before you buy. I try to describe everything the best I can. Thanks for stopping by and taking a look.
