Up for your consideration is an antique Illinois Engineering Co. Automatic Vacuum System Gauge #1. It was acquired from a local estate we recently liquidated. There is no original packaging or manuals included with this item and being an estate find I am unfamiliar with its prior history regarding storage and or use. Untested and selling As-Is. You'll be receiving exactly what you see in the photos. The front and back are 6 1/2" wide, the dial is approx. 4 1/2" wide and it's 2 1/4" thick. We are an estate liquidation company and are not experts on any one particular product, so please view photos closely for details and ask questions before purchasing. All items are sold "As-Is, Where-Is" with no warranty implied. Please refer to the terms of our return policy. Buyer pays return shipping.
