I actually have some. I bought a ton of them a long time ago, and didn't end up using them all. I've since sold most of my WPC games.
I have 3 LED OCD and 8 GI OCD sets. All of them are in the original packaging with the instructions.
Sorry I don't have a 4th GI OCD, but I could get you 7/8 of the way there if you're interested.
