If this not a Duesenberg Radiator, what is it? For the last 20 years or so I have had this radiator and never properly identified it. It was sold to me by Alec (A. K.) Miller of Vermont, the Stutz owning recluse. It still carries the number 7 on the core, in general it resembles a walking beam Duesy radiator, but is it? It also resembles the radiators used on some early racing Hudsons at the Savannah races maybe they were Duesys in disguise? More info on that radiator. 32" (815mm) tall, including the neck. 20" (510mm) wide. ID number, 8128 stamped on rear. Tag from manufacturer or repairer,on the rear, marked 'Pat Pend, El Arco Radiator Co, New York, Patent number 486065. Applied tag with number, possibly after repair, 9210. I have also included a photo of the cap, it is very distinctive, with an inside thread, ie the neck filler has an outside thread. Also note that it has trunnion type mountings to the chassis, identical to the system on a 1918 Stutz for example, American in style, not European. The very small inlet and outlet pipes are a modification that I did to test it on my central heating system in France.
