Since nobody answered your questions I will. You are correct, your pump was born in December, 1950. The 978160 verifies this along with the 12-50.
Nothing on-line, but there is a "Blue Book." This was published by the "Gasoline Pump Mfg. Association." There are three editions, information for you pump came from the 3rd Edition.
These books were complied to encourage gas pump dealers to scrap their old pump for the war effort. The first edition covers 1927to 1941 (WWII); 2nd 1942-1947, this only covers pumps made after 1946 when the war ended; 3rd 1947-1952, (Korean War). But the big thing these editions only covers the pump companies that were in business at that time. In my two gas pump books I identified over 125 gas pump companies, my 3rd book will cover between 175 and 200 gas pump companies. Very few of these companies survived the depression and are not covered in any of the "Blue Books).
When the Tokheim company went out of business in 2002, some people in Ft. Wayne purchased all the pumps that were on exibit in the buildings. They were also able to acquire all the files indicating when a pump was made, anything special about the pump, and possibly who purchased the pump. There are thousands of these records, I have seen them. The pumps and some of the files are now at the ACD (Auburn-Cord-Duesenberg) Museum in Auburn, IN. There is hope that the Museum will display the Tokheim collection and hopefully the other two companies that made gas pumps in Ft. Wayne, Bowser and Wayne. I donated a Bowser pump for the exhibit.
