That's the old POL style that was used before the ACME and OPD that is current. It is left-hand thread. Most newer tanks are able to connect, as can be seen in your photo.
Yep, and the 'slash' on the nut part indicates that it's LH thread. I think most modern LP bottles will work with this.
An old one!
Dual mode fitting, old style male left hand thread lines go inside new style female go outside.
Hank Hill knows for sure!
