Hi Derek. Sounds like you have one of the really old bottles with the different thread size in the neck. Unfortunately, there were a few bottle companies that came out with those back in the day and noone makes a regulator that fits those bottles anymore. You would have to buy an old reg with the larger threads to be able to use that particular bottle.
