On the "get more tools" theme: if you get a set of vernier calipers* you can just measure the cones for yourself. That way you can get exactly the wrenches you need. Afterwards (this is the really good part) you will be able to use the calipers to accurately measure chainline, head tube diameter for headsets, rim widths, axle spacing, stem clamp diameter, seat post diameter and a whole lot of other useful bike things. It's an awesome tool to have around and they're super cheap if you get a lower end one. I got a pack of six plastic calipers from Lee Valley for $8.
* Vernier calipers are sliding calipers that fit both around objects and inside holes; they use an ingenious low tech principle to let you measure accurately to a tenth of a millimetre or 128th of an inch.
