I had a 6 ft single sided awhile back that had same holes , I always assumed that’s how they lined two single sided big signs up for the pole configuration

The hole at the bottom middle of Chucks second picture IS for mounting the sign. The spot in question is the neon tube mounts in the white ring portion of the sign (they are not necessarily holes, per se).
They almost had to have kept the transformer in that area right below the sign. Not sure if that area is just welded shut or has an access panel on it. Be nice to see an original set-up. I'm assuming you are trying to neonize it? You would think there would be two insulator holes coming out the side, but nothing in this set-up here. I havent seen any signs where the insulator holes go straight up, so not to catch rain. Have you figured out if the neon was white or green?
