Don I have never seen a five quart Signal and don't think they had one.
Sam Mosher had one problem with his idea to capture this natural gasoline he needed $4000 to get the idea running and one of the large companies let him tap into there well. So he borrowed towards his inheritance from his mother because his dad thought his idea was crazy. Shell oil company was the large company that let Sam Mosher use there well site. He got a couple college buddies together and off they go. Signal products company was born. They had no gas stations at this time and were just getting this natural gasoline which if run by itself produced large holes in engine pistons. Very high octane volatile stuff but when blended with gasoline would make great starting fuel in the winter and more power like adding ethyl.
Below are some signs and other Signal items from the collection of Fred Stoke.
