OK Lars, you didn't want to separate the Kenner and Palitoy Droid Factories either, so here goes...
For anyone unfamiliar with the differences between the 2 sets, it's not just the packaging which differs. Although more similar to each other than either of the Land of the Jawas or Cantina playset pairs, the two versions of the Droid Factory still contain significant differences from one another, despite all the droid parts being the same in each set.
However, before we begin I would like to highlight a couple of (hopefully!) interesting things about the Palitoy Droid Factory. Firstly, it is the only vintage Star Wars toy with a partial name plate on the packaging. Eventually of course, both Kenner and Palitoy dispensed with the name plates on all of their toy packaging apart from the carded figures (which kept them to the end of the run), however the Palitoy Droid Factory is the only one with the job half-done; it's missing the oval surround around the name:
Secondly, the Palitoy Droid Factory plastic base comes in two completely different colours, despite its packaging not changing. A few other toys also changed colour during their production runs, but their packaging usually changed at the same time, e.g. the TIE Fighter comes in both white and blue versions, but its packaging changed at the same time. The white TIE Fighter is never found in Jedi packaging and the blue one is never found in Star Wars or Empire packaging.
However, the Palitoy Droid Factory base came in both canary yellow and blue versions, despite the box never changing and only ever showing the blue one. When you bought a Palitoy Droid Factory, you had no idea which version you were getting until you opened the box! Incidentally, my childhood Palitoy Droid Factory was a yellow one, and because I never bought a second one (well, why would I? ;-)), it wasn't until adulthood that I learned to my considerable surprise that the blue version also existed! Prior to that, I'd simply assumed the blue one shown on the box was a misleading con, and I was even quite cross and disappointed about it as a child as I wanted it to be blue to match the one on the box, which I thought looked much better! :lol:
Interestingly, the base of the Kenner version also comes in two colours; a light brown and a darker brown. However, the toy was reissued in Empire Strikes Back packaging with its original light brown base, and it was, to the very best of my knowledge, a late running change in its new Empire packaging which saw the base switch to the darker brown version. I do not believe the darker brown one ever came in the original Star Wars packaging, but I am of course happy to be corrected if I'm mistaken.
Lastly, for those that don't know, the 3-legged R2-D2 which came with these sets has a sticker which is a mirror image of the regular carded 2-legged R2-D2's sticker. God knows how the error occurred, but it does at least help identify some fake stickers for the 3-legged version once you know about it!
Also, the Palitoy and Kenner versions of the stickers are not the same, making each set's version of the 3-legged R2-D2 unique.
Anyway, the Droid Factory!:
