I know this is an old post.. But I offer nos leaf wicos. Have a small amount of the 3.5" kind, every ball color except black. Also sell refurb'd leaf joysticks with nos parts.. Only used parts are the bottom half of the joystick (holds the leaves) and the plastic leaf insulators (no repro's or nos available). These come with nos leaves, grommets, sticks, etc.

Look me up on klov: local413
Does anyone offer repro leaf switch joys? Doesn't have to be a Wico.
Or am I stuck using the leaf switch/microswitch adapters?
