Heres something Ted's not telling you. By the late thirties signal has bought a controlling interest in Billups, Watson,and a few other companys in the south. in the late 40ties they even opened Hancock stations and Signal stations down there.
One of our members asked if signal was ever in the southern states . He said ,He remembered as a kid going to a Signal station. 1947 , Signal was asked to lead an Expedition, of drillers from different companys to drill and tank oil in Saudi Arabia , by the time Sam Mosser was ready to retire and his Nephew took the CEO spot, Signal was drilling all over the world. Being a Cali guy and finding many pumps in the beginning of my collecting, along with a friend Ivan (who at one time had a large Signal collection) we found that around 1937 when the pump manufacters started using larger ad-glass in thier pumps = national A-1,B-1, national A-38, signal had no need for globes. and stopped buying them. as did a lot of west coast companys. of course 1941 World War II, Civil defense took care of a lot of West Coast globes.
