I've seen those green ones before, described then as repainted green.
I think white was the color för Supersonic Zickos.
Tried a kit once and they sound great, and they are heavy!! I also tried to buy that kit a couple of years ago but they were "not for sale, ever!" And I think they were darker inside the shells, glassfiber structured.
The local store, the Swedish distributor for Zickos, also had two "timp-toms" looking like upside down damejeannes in clear acrylic - should have bought them...
