Without pictures of the pump/globe this is just preliminary estimate around here in SC -
If the resto was decent but showing a bit of age (dulling) figure the pump without the globe $1000-1200 .
If the resto still looks pretty good 1500-1800avg.
Add the globe value to those figures. If it's the more common globe it might only add $300, but if it's uncommon/rare then the price goes up of course.
Those figures are based on complete pump not missing anything and resto was in line with correct Gulf paint scheme.
Figures can go higher depending on location, but T-39s are one of the most common seen restored. Meaning you can wait and find one in those ranges.
