>SCR-18...Manufactured by Pro-Lite however...
I went and found one of my globes, they are Philex "Eco Lamp" branded. No sign of who the actual manufacturer is though.
Osram` Centralux sounds intriguing - I have never seen one of those. Philips SL-P and SL-C were quite common in the supermarkets here at one time however. When I was much younger we had an SLC18 in our toilet that stayed on all night and must have lasted a good 10 years before it finally died of old age. They might be big and not as efficient as some modern electronic units but they were certainly of a high quality.
And that plastic lamp is just wierd - nice find! I have a lamp here that is tubular shape with a string of nine little low voltage bulbs like those, only they are wired in series for 115 volt operation. It`s Japanese I believe, and could have been intended for US style exit signs.

It would not surprise me if your little globe was made in Japan also, but when I first saw the photo this morning I would have sworn you`d made that yourself! Has a very primitive home-made quality to it.
