Antique vintage brass engine/machine oiler in excellent working condition; very minor \'wear\' as shown. Metering needle valvelooks straight/good; shutoff valve\'s stem is straight and shutoff feels positive. Both \'bullseye\' sight glasses are clear with no cracks or visible surface abrasion. This machine part was apparently used, kept in good condition, & wiped down until quite recently.
Ex-marine engine room application (steam-driven bilge pump?) Ship\'s identity is unknown to me; salvaged sometime during last thirty years at a Portland, Oregon shipyard.
