Bartie, please listen to me. I really recommend to go there by daylight. The place is a complete MESS and the danger of stumbling over some of the debris in the dark and getting serious injuries is very high!! Plus you won't see very much unless you install some serious lighting to light up the whole area.
Go on Sunday, or rent a room in Worms from Saturday to Sunday. This place is abandoned (except the assholes who go there to even increase the mess) and there's a decent distance to a hous with people living inside so no one will be disturbed on Sunday.
And don't forget to bring a cordless screwdriver. You also might need some drills to remove rusted screws....guess where I know from
Ol, I already pulled the bezel of the Grand Champion. You never mentioned the other parts, only the bezel. The controlpanel was broken, what could be pulled is the wheel, the shifter and the gauge(s). Don't know if the wood with the score display can be easily removed. We (ajhippel and I) had some trouble getting the bezel out. We had to go from the back and removed the monitor. Maybe it's only removing some screws to get the whole thing out.
The controlpanel and the bezel of the Field Goal are gone meanwhile, don't know who got it now
Marquee and PCBs had already been removed before.
Good luck, guys!
