Hi Cathy,
I'm not sure what you are after.If you just want a list of companies,you can add these:Gulf,Shamrock,Whiting Bros.,Conoco,Humble,Malco,Hedges and Horn.And I'm just mentioning a few from Texas,New Mexico and Arizona.If the mid-west and west coast guys weigh in,I think that list is going to get a LOT longer.
If you are asking which of those companies you can get reproduction/fantasy signs for that is another question.I will note that if you include fantasy signs in your plans more small signs will become available IMO.Hope that helps.There were a lot of them and some of them operated only in certain states.Good luck.
