This 11 inch glass oil lamp is a 1970s to 1980s replica of the antique Diamond / Dominion Bullseye Fine Detail lamp, likely made by the L.G. Wright Company, which went out of business in 1999. Although the lamp has a very faint sun purple coloring, the collar appears to be glued on and the bottom is too free of wear, nicks, or scratches to be 100 or more years old. The brass Plume and Atwood burner is actually quite a bit older than the lamp, which is not uncommon. The lamp is in excellent vintage condition with no damage.
