Very cool on the artwork progress.
I got a notification on the thread - so probably a good time to update it...
With the help of some of the awesome UK collectors, and Ed Lutz here locally - I am now fortunately to have two full Quasar boardsets with sound boards. So hopefully, I should have some luck there.
I also have two marquees. I bought one off eBay for what I thought was a deal. Turns out, the seller deliberately hid that the front was scratched to hell, which you couldn't see in the photos. But fortunately Thorsten came along with his NOS ones, and I bought one off of him.
So - all that should be left is the harness. To refresh that question - can anyone help me there with some photos as an initial compass? I know that is an ask on someone's time, understand if it isn't possible...
