Build Tips
Check the piece count on the bag against the parts list before starting — knowing what you have prevents mid-build surprises.
Even in small sets, connection order matters. Follow the steps rather than building sections independently.
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 #349 (1971) 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.
