Build Tips

1

Check the piece count on the bag against the parts list before starting — knowing what you have prevents mid-build surprises.

2

Even in small sets, connection order matters. Follow the steps rather than building sections independently.

3

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.

Finding Instructions

Instructions for older sets like #1347 (1987) may not always be available on LEGO.com. Try searching the set number directly, or upload a photo of the bricks to LegoFinder — the AI can identify vintage sets from their parts.
