In 1965 Signal had closed it's retail gasoline business and was sold out to Enco out here on the west coast. Out of the gasoline business but not out of business. The space industry was where their efforts went. If you look at any FRAM oil filter you might see Signal Co. on it. Is it the same Signal Comapny that used to sell gasoline. I have been told it is. Believe it or not.
Below is a rare picture of the first Sign used for Signal Gas in 1931. Anyone who has this sign has a rare piece. Ted
