Antique Judd Mfg Letter Rack/Holder-Mirror Image Maidens-Art Nouveau-Cast Iron

I believe this is an antique, Judd Mfg Co letter rack/correspondence holder dating to the early 1900's. Some research suggests it's cast iron (it's magnetic), possibly with a brass finish. A double-sided design of two fanciful lady profiles accented with flowers and stylized art deco accents. Despite scrutinizing the rack with a magnifying glass, I was unable to locate any markings or mold numbers. Approx measurements are 5" long by 4.5" high by 3.75" wide. I've not attempted to clean or polish.
