Destroyer Droid

Running changes occured early in this set's production, perhaps before any were actually released. Notably, the Rubber Bands/Belts differed, but at least some set copies include the parts for building the set either way. An errata book can be found with the copyright 2000 original release instructions. Numbers for the original release instruction book are 4133106 (North America / English ?) and 4132567 (Europe ?). Numbers for the errata book are 4131258 (North America / English ?) and 4131259 (Europe ?). The errata were later incorporated into a new versi,/on of the instruction book, 4133412, also copyright 2000.

As reported by one seller, copies of the set can differ in weight by about 1/2 ounce. The lighter copy contains a single page "Amendment sheet" numbered 4133085 with instruction book 4132567. The heavier copy contains a 6-page "Amendment sheets" numbered 4131258 with instruction book 4133106. The heavier copy also contains 5x red rubber belts (possibly x37) loose in the box. Unlike the instructions of the presumably earlier versions, the six page amendment pages clearly show the red rubber belts.
