Sorry Joe, about all I know is in the above link. The site wasn't very user friendly. I tried some searches on your lights, but I think it only searches text files which would be new patents only. All the old ones are images only, which means you will need a number. Perhaps an old manual in a library, or maybe a sneak peek for a stamped number in a museum (watch out for those curators if you're behind the velvet ropes). There were some ads on e-bay. The text wasn't readable however you might be able to guess if a small block of text looks something like "Pat. Pend." Never fear, the patent I found was in the 2 million range and it was from the mid 30's. Your lights should be near by, +/- 250k or so.
best of luck
