Dietz Vesta railroad lantern burner and cover. Not threaded, this pushes in and friction holds it in place when the assembly is twisted about a quarter turn in lantern. 7/8\" opening. Turns freely but wick is old and doesn\'t engage very well. I trimmed it a bit after taking the photos and it goes down easier than going up. Nice patina with light surface rust. Please ask any questions before offerding. IL residents not exempt must pay 9.75% IL sales tax. Thanks for offerding!!!
