11/2/20 - This is an original US WW2 era grenade with an original case / container. The grenade is inert, and the top can unscrew from the body. Excellent condition with some light patina throughout, as shown. Research tells us that the top was painted yellow during WW2 for the pacific theatre, so this is most likely a late WW2 production grenade. The original container is included and completely in tact.
