Antique reed & Barton sterling silver gravy boat & under plate tray about 11 oz

you are getting an antique sterling silver Reed and Barton gravy boat with under tray. it weighs 311.4 grams which is almost 11 oz I do not clean any silver. I like the old look to it but if you would like to clean it I can recommend what I would use to clean it with which is a gun cleaner called Flitz. if you have questions just ask. this piece will always hold value great time to invest in silver
