'53 Slough dash. What goes where?

This car was such a mess, I had to throw the old dash away. It had more holes than a colander.

I’ve scoured the internet looking for some ’53 Slough Light 15 dash pictures. My best guess is ignition switch and oil pressure light in the first cavity (nearest the door), the speedo, then amps/clock/fuel guage, then maybe selector for the trafficator? I’m not a purist, but guess that will look roughly correct!

I’ve cleaned this metal disc up, and I guess this should contain and ignition switch, and oil pressure light, and maybe another switch or two? Any ideas or pics will be gratefully received! Thanks.
