Check the test certification date. It has to be done every 5 years. They could be of legitimate ownership, except that the certification has expired. You could have to pay to have them tested and recertified before they can be filled. That's not terribly expensive, like $12-20, but it is a hassle. Most of the places that fill CO2 tanks can get this done for you, though many of them need to send it out which can take a week or two.
