Mini Lego MTT / Multi-Troop Transport (Lego 4491) - Released 2003
In Episode I a lot of MTT's came to conquer Naboo and get rid of the force field shield. They carry droids to the battle field (no droids in this mini lego MTT of course!)
The 4491 Star Wars mini building set was the last in a set of four. This MTT building set also had a part of mini Y-wing, that you can create if you have all 4 boxes in the set. The other boxes are the Millenium Falcon (4488), the AT-AT Walker (4489), and the Republic Gunship (4490).
According to the box, this set has 99 pieces, which includes the parts for the mini Y-wing of course... This mini lego MTT has very nice colors, and another example of how good they can make these look!.
