    A pressure gauge of some kind found in my parents garage loft. I am unsure but could BRM stand for "British Railway Midlands?" or could it be some kind of pressure measurement abbreviation?

    It has a wonderful patina to it copper body and a beautiful cream colour on the face which is concealed by a clear glass.

    Depth = 5.3 cm
    Diameter = 18 cm
    Weight = 1.5 kg

    Do you know anything about old steam engines or pressure gauges? if so I would love to hear from you.

    Thanks for your time and I hope you like my latest find.

      I have never seen a steam pressure gauge marked other than psi, or psig. But after a Google search, it appears you are correct. Also, I would also bet it was used to read steam pressure as well, so you had it correct on both counts imo. PS: I saw one site where they were converting the workings on these old gauges to make clocks!? Go figure, and Nice Find!

      Wayne, thank you for your reply I appreciate it. I will look for those converted clocks, sounds interesting. If it was p.s.i would "175" seem the correct kind of pressure for a steam engine? I say 175 as it is marked in red.

      Cheers,
      Matt.

      Matt: Yes, it very well could have ran at 175 psig, depending on the engine size, and use requirements.

      Usually when a gauge has a red indicator it is usually for limits or a danger condition. Has pressure been applied to test this or is this revolution counter operated by a driven cable such as a tachometer? Could you post a better photo of the fitting?

      Yes I suppose your right there, red is normally danger. Bear with me and I will get a close up of the fitting for you.
