The lantern itself (not including the cord or hanging handle) measures about 8 inches tall and 7.25 inches across the base. It has lived a long and varied life ... at one point it was red, then painted black, it now has scritches and scratches and rusty spots, red and bare metal peaking through wherever it has worn, and knocks that wobble the circumference and bottom of the base. The glass appears to be a replacement piece, that fits and suits the lantern. It's a great look for spare industrial spaces or cozy nooks.
The lamp works just fine, the electrical is good, but it is also very old as you can see from the photographs. I tested it for quite some time and everything looked functionally good - no unusual heat build up or wavering light - but if you plan to use you might like to add new cord and plug to be extra safe, and to lengthen the cord, which is quite short. The cord here cleverly comes out of the old gas filler/pump hole instead of out the bottom, which leaves the base clear to sit flat.
A character-filled and historic little lamp for a side table or screened porch.
