Redesigned during production.
There are at least 5 different versions of instructions for this set. The first 3 one-book versions show the same parts and build. The differences for the two-book versions are indicated in this inventory in the Alternate Items section with Match ID 99.
Quick overview of redesign: A major rebuild involving the trailer roof and a number of basic part substitutions, including replacing all 2 x 4 plates with 2 x 4 plates with holes. Although the trailer roof shows more differences, some of these parts are also used in the alternate build. |
