économies Rare ! Ancienne étoile en laiton Mfg. Co. Jauge vapeur Steamfitters Pipefitters Boston

This is a pre-owned antiquated brass steam gauge thats in acceptable overall condition. This gauge is being sold as is! Ive decided to keep its original patina instead of cleaning it up. Dont know if it can be functional? Its a 6-inch gauge. The front cover measures 7 and 1/4 inches in diameter. The back side cover measures seven and a half inches in diameter. There is oxidation and marks on gauge. Also, there is a nick on économies the brass cover. See picture. The gauge surface is discolored but legible. Please review pictures carefully as part of the description.  Please note that international buyers are responsible for any customs, duties or applicable fees beyond the purchase of this product. Thank you for your time.
