So I joined the club too, I bought a machine someone with little knowledge was trying to restore, they kinda fucked up the playfield by clear coating over dirt and damage, not to mention insert decals, not much I can do about that unfortunately but it doesn't seem to affect the ball rolling so I'll try clean it up as best I can.
there is a lot of snipped wires and a couple of things missing from playfield
I'm wondering if someone could tell me what is missing from here, guessing GI Relay board (C-11902-1), marco shows it but not in stock?

I'm also looking for this panel, a repo will do, I'm aware of this one on ebay but the condition isn't very good

Thanks, I picked up a second hand one

Cool, I’ll have a look at that mechanism and see if I’ve the parts to fix

Picked myself up one of these that someone made an arse of restoring, they over tightened every single rusty screw until it snapped each starpost, snipped a load of wires, clear coated the playfield over dirt and raised insert decals.
I'm in the process of bringing it back to life, sanding down the clearcoat a bit too much for me, I'll leave that for another time, for now its, polish and wax the playfield, new plastics where possible(if anyones got any spare plastics they are willing to part with), all new star posts, polish the screws
Here's a few pics, it actually came with Hurricane slingshots which I think look really good

Does anyone know where I'd pickup the "Ride the comet for a million" plastic on its own, really stuck finding one.

That's the one, I may have sourced one (fingers crossed)
