I'm in the minority of Pinsiders that like this game. When the game set up in a dark room is great to look at. The ability to actually hit the ball backwards with the flippers is fun. Hitting the drop targets is challenging. With all of that clear plastic, Novus is going to be your friend. "Shoot Pinball, Shoot Pinball".

Back in 1982, I went to the local Gottlieb parts supplier to get some parts. In the showroom had a few pins and arcade games on display. While waiting for the parts guy I usually played a few pins. One day there was an Orbitor, I started playing it, a another guy comes out from the back and naturally states, "Hey Kids this is not an Arcade". He finally looked at me, I said, 'I am waiting for the parts guy'. The parts guy nodded. So the sales guy then asked, 'What do you think about this game?" I said, "That is unique and totally different. Clear curved playfield and the ability to hit the ball backwards is bizarre." Then he thanked me for the input. I never saw one of these games in any arcade locally. (Greater Vancouver). In a darker room this game stands out, brightly lit room with worn playfield it just looks so so.

Could you use Velcro strips. 1 side glued to the carboard, the other side glued to were the light fixture needs to positioned.

Looking at your photos.

The cardboard rings look like they are to be attached to the underside of the playfield securely. Removing the bulbs requires squeezing the metal parts of the lamp base. Pulling the metal base out of the tube.

New replacement light shields could be made from plastic. If you used Velcro, you will need to cut the Velcro into squares, and removing a circle of material to allow the light to shine through. On the light tubes the velcro will have to folded back and glued onto the outside of the tubes.

Those cardboard light tubes are pushed onto the playfield bottom, are they held by friction or is there evidence of a glue being used?

Plastic tubes could held on with surface tension, by putting thin tape on the posts for the lights. Ever so carefully pushing the tubes in place. Some care must be taken as that underside playfield plastic may have become brittle with age.

This sure proves how different these Orbitor 1s were.

Could of been 3M Automotive trim Adhesive. It was cheap and lasted a long time and is yellow or black.

Do not know, but a guess would be the name they used for pre-production, since the playfield is not flat.
