Jerry, thought I could put my finger on a better picture of a pump at a station for you...I need to get my literature more organized. But I hope the following pictures help in your restoration...
An original GOC National clockface as pictured at the farm before I removed it for safe keeping in my shop. The former owner of the farm worked for Gulf during the 1930-50's.
Next is a pic of an orginal No-Nox Ethyl decal.
Next is an original No-Nox Knockproof pump plate and was also a decal. I also have this in an orginal decal but the plate shows better in the picture and matches the decal perfectly.
As for the globe a standard three piece GULF that I believe the lenses are 12.5. But better check with those who know their globes! Hope this help in your restoration. I try to do the same in my restorations, as close to original as possible.
