Question about a fire hydrant

I had a question about a particular style of fire hydrant (Rensselaer, above). The hydrant itself is not one I have been able to operate or service. From what I have learned, the company that makes this style isn't in operation any more. I managed to find pictures and information you can access at Firehydrant.org here, the folks that operate this website have really done their homework. Most of the fire hydrant photos I have posted are from their website. I reccomend visiting FireHydrants.Org for any research into fire hydrants.
