I have seen a number of these things for sale on eBay and noticed that when they have a key it is always symmetrical. That has led me to wonder if the layout of the levers is symmetrical inside the lock or if the symmetry of the key was just to allow the key to be inserted either way. Your asymmetrical key suggests that the latter may be the case.
