Ludlow Valve Mfg. Co. - Troy, NY List 90 and List 90-0 |
|
The List 90 has a unique octagonal barrel and nozzle caps. As documented in an advertisement from the 1930s, it was originally called the Ludlow Diamond self-illuminating Fire Hydrant. It has a two piece barrel with
a conventional bolted flange joint. It later evolved into the List 90-0 model shown in the
next group below.
It was produced in at least 3 sizes from the early 1930's to the mid-1960's. Only the later hydrants are dated. Here is the first page of the
List 90 design patent which
was filed by the inventor on January 29, 1932.
