This American pressed glass oil lamp with tri-mold marks measures 7-1/2″ high and has a classic gadrooned body design. It is not uncommon to find glass oil lamps with replacement bases, as these were handled often over the course of each day and accidents did happen. Please check out my other oil lamps to see replacement bases created in various styles and made from an array of materials
A wood replacement base with silver gilt surface was probably made in the 1920’s-30’s, as is evident from its “art deco” look
The oil lamp below with a similar shape still has its original glass base, a lucky survivor of over 100 years of use
