I have a 19 L Mytton corny keg
Its a racetrack lid and was made in Australia, so I guess yours would be too. When I got it it had some really weird disconnects on it but I changed the posts to ball lock ones. The interestingthing about it is the posts have a male thread and screw into a 1/2" bsp fitting on the keg where all of the US kegs have posts with internal threads and the kegs have the male threaded bits on them.
Cheers
