I got this from the widow of a older gentleman who was a collector who passed and she took his collection to a local show. this is a hand grenade type or some might call a keg fire grenade from Spain but I just don't know and have not been able to find anything about it or the company's history....it is a light lime green and right at 7 1/2" tall and what looks like a crudely tooled top, the embossing on it is CARBO HERs Y Ca BARCELONA with the s and a of HERs and Ca being smaller capitalized letters with underscores. Just not sure of any info or value. There was a smaller grenade with multiple sides from the same embossing but another guy had latched on to it and ended up buying it. Would have loved to have gotten that one too but no such luck. Thanks for looking and hopefully there is a fire grenade expert out there that knows about these. HH Ace
