Ryan,
There were two main variations of Sinclair US Motor Spec globes.
The first design was white with red lettering.
This design was normally a 3pc glass globe, but Sinclair used decals on a regular glass body too. This design dates from the late 20's through 1933. The pumps used ad glass and decals to match the globe. According to the pump resto book the pump should be white with red base, top and horizontal features.
The second design US Motor Spec globes had a wide green or black band across the lower area.
Add glass and decal matched the globe. This design dates from 33-at least 38. Pumps were solid red.
Be sure to post pictures when you're done. Better yet take before, during and after pictures and walk everyone through the restoration process in a Restoration Of The Month feature!
