    Went out to do discovery today...some of you old timers will enjoy these.

    Will post a close up once someone nails it.

    Would help if you had a better picture of the valve, instead of the vacuum breakers :)

    I have a better pic, but then that would take the fun out of it. How many 4 bolt bonnets on a brass valve are there?

    But since you asked.

  4. I'm guessing royal coach/buckner

    Four-bolt bonnets would be the norm on a one-inch valve. Solenoid looks like a Buckner or Royal Coach.

    I would have said W*M on the basis of the bonnet, but the solenoid seemed different, somehow. An enlargement does show some of the S24B shape.

    I had a lot of stuck-open service calls on those, mostly on older ones with the big green solenoid. New diaphragm, and a flow-control stem installed, and they were good for years to come. Maybe some corrosion to scrape away from the valve seat, or even a film of rust on the solenoid plunger.

    The old green solenoid was an odd one. No spring, so upright valve position only. The solenoid seat in the bonnet contained the rubber - none on the plunger.

    One design flaw on the early W*M valves was a port in the bonnet (instead of ports in the diaphragm) that used a tightly-wound-spring as a filter. That arrangement would get clogged, and a new diaphragm was the cure.
     
  9. I think you may have it. The solenoid as boots says looks off. Could be the view or angle.

    I wouldn't base it solely on the solenoid unless it's verified as original. There's a couple of "universal solenoid" kits out there with the larger thread patterns that fit most of the older brass valves and they have different shapes.
