Here are a pair of REPRODUCTION brass and tin-plate screw-in whale oil lamp burners that have 7/8" [ #1 size ]  threading. These burners fit standard American brass collars but would not fit antique all brass lamps that many times had a coarse thread.  The tubes are about 1 & 5/8" long. The brass and tubes have been darkened, The burners are not an exact match but they are close to an exact match. I ship to the Lower 48 States ONLY, with a shipping charge of $5.00 on this lot. THANKS
