Who made these ... any ideas.

John sez .... That third rail piece you posted was made by Ohio Brass, up until the early 1950s - They were used on the Lackawanna & Wyoming Valley RR which I used to hunt back in PA, and then another line in NJ used them as well. Some have really nice drippy glazes, like in the picture I attached...but as usual the best ones are the most beat up.
