Bob, correct me if I'm wrong, but that would be an AACO then, not an ACCO.
Seem to be a few of these for sale at the moment, and coming back down to a more realistic price, it seemed to go through the roof a few years back. Always wanted one of them, but it came down to a choice between one of these beasties and a matsterpeice of Pommy engineering.
AULRO.com has a bit to do with these, probably a good spot to start.
