Parco was the name for the Producers and Refiners Corporation. I believe they were a consortium of, well, oil producers and refiners. A bunch of smaller companies rolled into one. There is a lot more info somewhere, perhaps in Wayne Henderson's logo book. I think I have an extra Hawkeye Oil and the 1932 map if you're interested. PM me if you are. The conquistodor map is from 1931, the other with the spotlights is from 1932.
