Rounding out the 1979 and Star Wars line is the Droid Factory. The Droid Factory was 56 pieces (if I counted right) of building fun. An endless number of different droids could be made with this set, a long with a special three legged R2-D2. The blueprints showed how to make 5 (?) droids to you to started with and left the rest to you. The other main featured is a crane to aid the Jawas in droid assemble. The base can be used to the store the droid parts in. Released in 1979 and was available until the end of 1980. For the 1980 release the box's art work got rework in addition to the ESB logo.
Palitoy released a completely different version of this toy. The base was vac formed in either blue or yellow plastic. And although it has a similar ramp, it lacks the crane and where the individual parts are stored is different. In place of the crane Palitoy added a conveyor belt. I believe there few fewer parts as well (if someone could correct me).
Let's be honest the Droid Factory wouldn't enjoys half the glory it gets if it won't for the three legged R2. Without him this would be a pretty ho hum playset. Most of the droids that can be made are pretty lame looking in my opinion. It might have been cooler is the Droid Factory fit in or came with the sandcrawler. Over all I don't have a lot of good things to say about it other than the R2 figure.
