I have a 1939 National C-38 Gulf pump in restoration progress. I need to find some round signs for it, however none that I find have found have the correct measurements between the old holes from previus signs. Measures 10 inches between holes. Also I need a switch handle to turn lights on and off. I am fairly new to pump restoration, but learning. Should this pump have (That Good Gulf) or just plain(Gulf)? Thanks Tim
