Great find !
Which handle is missing ?
reset handle or the nozzle or one of the hose guards that look like handles.
The reset handle are reproduced. also the V-embleme or the stainless trim that was on some pumps without the V.
I saw the pump on ebay and i would save the globe original and buy a repro glass globe and use one of houndred sort of 13,5" lenses avalible.
If you put a decal over the gulf logo it will shine trough decal if you have a light inside the globe.
there are a few that sell the glass globe for 13,5 lenses but have you check this company
