Hi, Tim! Glad to be a new member of your forum! The repro bubble light stands do not have the "Made by Royal" cardboard bottom cover, and the wiring in these stands is new vinyl covered rather than the older cloth or rubber. Also, the cords on the new stands are much longer than the originals- 9 feet long as opposed to the original 5 foot length. Additionally, the sockets on the originals are permanently inserted from the top, whereas the repro stands have their sockets attached from the bottom. To my knowledge, the rarest color is green. I've seen these stands in red, green and marbled white/beige. The green sells for more than $500.00, with the others bringing prices in the $300.00 range. The stands were originally packed with 9 Royal "crown" style bubblelights with base colors EXACTLY matching the stand they were packed with. Examples in good condition, with all original lights will bring the prices I've mentioned above. Hope this helps!
