The 1955 list was for public corporations deriving at least half their income from mining or manufacturing. (That's why Ford isn't here.) Perhaps that could be made clearer in the introduction. Fortune started publishing lists of the top 50 retailers, banks, insurers, utilities, railroads, etc. in the 1960's and eventually merged them into the current list. (Something similar happened to the Dow Jones Industrial Average.)
Please accept just plain old "Swift" for Swift & Co. Citgo was Cities Service in 1955. Before the 1984 breakup of AT&T, what is now AT&T Technologies was called "Western Electric", the manufacturing arm of AT&T, since AT&T itself didn't qualify under the rules. Please also accept Socony Mobil (the formal name in the 1955 list is actually Socony Vacuum) for Mobil (Socony stands for Standard Oil Company Of New York). I really doubt that Goodyear qualifies under auto parts, let alone autos; together with US Rubber (later Uniroyal), B.F. Goodrich and Firestone, it was part of Big Rubber. And I think Goodyear made more than tires (tyres) anyway.
* The six 1955 companies that would have been in the top 20 under the rules of 2004 but not under those of 1955 were: _3. AT&T or American Telephone & Telegraph (the operating system) _4. A&P (Great Atlantic & Pacific Tea) _6. Sears, Roebuck _9. Metropolitan Life Insurance 12. Prudential Insurance 13. Safeway Stores.
Under 2004 rules applied to 1955, the Texas Co. (Texaco) would have been 20th, Western Electric (AT&T's manufacturer) 21st, Shell 22nd, National Dairy Products (I guess Kraft) 23rd, Equitable Life Assurance 24th, Socal (Standard Oil of Calif) 25th, Kroger 26th, J.C. Penney 27th, Goodyear 28th and Boeing 29th. Sinclair Oil would have been 30th, International Harvester (now Navistar) 31st, and RCA 32nd.
