Could be lots of things, it is most certainly from the A-pro factory, I saw one of their catalogues once, it was like a phone book and certainly opened my eyes of alloy frames...
RaceFace Taper lock stainless, the one with the red cups, been running a couple of these for years now with no complaints, fully adjustable for chain line and 68/73 compatible.
Generally the ones with the longer levers and no crumple zone are Canti compatible. Some say the speed dial can make them do both but I have never found this to be the case.
