Just an FYI, I am not aware of any legal way to secure an AB keg. I would be hesitant to post pictures as I know they will send people out to pick up kegs that they see posted. (When I worked there, I was asked by the legal department to pick up a keg from a home brewer who had a photo in the newspaper with an AB keg. They do not sell their retired kegs and will involve law enforcement...if it says AB, it is theirs. I refused...stating that the keg was already ruined by the ball valve...but they are aggressively addressing the significant cooperage shortages)
I am not judging...just a heads up. If you have a keg with a major brewer marking, it is not likely legit
