Ford Benzol Reproduction Gas Globe shown here for reference only. Ford Benzol inserts with single strength glass were made in the early 1970s and never dated. That means they can be over 35 years old! I have maybe seen one original on three piece glass. That globe would be the thicker, double strength glass, with deep notches. Most Ford Benzol globes are either the Keyhole Shaped One Piece or the flat 15 inch inserts for metal frame.
