A look on the bottom will tell you who made it. Likely it has a SG on the punt if there is a punt. Then if you weigh the bottle and its more than 350g it will likely hold pressure. Bring a cage to test fit and you can prob use them. There are bottles with lips like that which are not designed for pressure though. Normally at that size they tend to have a crown cap top that also accepts a cage, except for Belgian bottles and a few other exceptions.
