Identifying W decays

In the following events a W+W- pair has been produced. See if you can identify which sort of particles were produced when the W's subsequently decayed!
Because there are two W's this is rather like looking at two Z's on top of each other. But remember: when W+ decays to leptons, one must be charged and the other an invisible neutrino. When it decays to quarks there are always two to be seen.
