A super neat Jas. P. Marsh Skokie Illinois square boiler gauge from about 1920. Measures water altitude, heat, and pressure. I have searched all over but NEVER see old gauges that are square, neither has some of the greatest steampunk creators I personally know. It measures 4 inches by 4 inches square. Glass cover with vibrant ink. Brass threads in back. Super cool piece to add to any steampunk creation or collection. Insurance included with shipping.
