Here is what I believe to be a Locomotive Break Test Pressure steam gauge. I believe it was from March 16, 1897. It Shows Boston on it, Please see pictures. I've had it for decades. Always enjoyed it. It is untested and sold as it is shown. The front cover over the glass unscrews. There is also a bonus gauge included C. A. Norgren co. Denver Colorado. Thanks for looking and hope you can enjoy it!
