Build Tips
A five-minute sort by color or piece type before starting saves time hunting for specific bricks mid-step.
Follow the numbered steps in sequence — structural elements early in the build support everything that comes after.
Vintage sets may show slight color variation from modern LEGO due to different ABS formulas. This is normal and part of the set's character, not a defect.
