O.K. - that settles it for me.
And I think I'll do what you did - make a completely new CP and put in a pair of WICOs. Playability first (and looks). But the building conservator in me will save the original CP + joysticks for posterity (a "reversible alteration").
But the Euro repro overlay: do you know where I can buy it, or who used to make/sell them?
