What year model is this machine. ?

The nice pastel colours of this era were definately pleasing to the eye. Looking forward to seeing it finished. Backglass ? ?

Is not pastel mate.. the pink and orange are fluoro colour... is a very bright PF.
There are differences in the artwork though in the Segasa and Williams versions, both in backglass and plastics....... the blue in Segasa version is much richer, but i think its the yellow thats weaker.
Interestingly the Segasa who it was licensed to had more detail in the art on the plastics than the original Williams version. Segasa also did not have the strange looking eye lashes on the girl in the BG
