I was just given an old keg that I believe may be from a soda fountain.The side of it says Bastion-Blessing Chicago,IL. The only problem is I cannot figure out how to open it.The top is similar to a corny keg except it seals externally to the top with the use of a cam lock handle that has a rod that runs through two ears on each side of the keg. you can loosen the lid by pulling back the handle but the rod will not disengage from the side ears unless one considered removing the handle from the rod which appears to be held in with two pins. I would appreciate any info someone may have on this unique keg
