Craig, That is a KR-43 in the poison books. They come in many sizes from 1/2 to 32 oz. The big 32 oz ones are scarce, but the smaller ones are common. I still like them, any poisons are cool to find. Charlie is right on with the price. These are cool to put together as a graduated set, and it won't cost you a fortune like a lot of poisons would [] Jim
