Lol 😂 I have one in my bedroom in a newer package (also Sylvania) because I swapped it out from an old Deitz oil lantern with a red lens my Uncle made into an electric lantern in the early 1970’s, so that’s when this was made. Circa 1970-1974. The American ones all had perforated electrode plates. St lest GE and Sylvania. Westinghouse never offered these. The GE ones had a different plate shape. Duro Test made these too and they had solid plates like the imported ones. The one in the lantern is imported and has solid plates. I took it out to preserve it as they are really hard to find. I have the spare to this one still, my uncle gave it to me on Christmas day 1972, and it is an ABCO madd in Japan and it is beautiful and incredibly well made. I don’t have the box for either bulb but both work perfectly, and I have the very flicker flame ever made and sold-Aerolux brand, circe early 1960’s! My Duro Test ones are in thar era too. The Areolux is in a T10 tubular bulb with ivory paint from the flame plates down to the base. Rate lamp! Avoid using these too much. They flicker because they are essentially burned out even brand new, with the “hunting” of worn out electrodes typical of neon glow lamps when the emission material on the plates gets depleted, so the life in use is unpredictable, some will do up to 1000-1500 hours ( still short life) or can fail in a few minutes. So keep this in mind. If it was mine it would stay in the package. Cheers!
