After my research This is Similar to the Hickok Beltogram. Used in the same way. The belt loop has a gold flower with a ruby gemstone in the center, vintage scroll work.
The chain tested sterling, as well as the belt loop. The closure is marked Nickle Silver.
Belt loop measures 1 1/4" long x 1/2" wide x 1/4" deep.
Chain measures 6 1/4" long.
