Based on one person building the set for the first time, following the original instructions and using numbered bags where supplied. Includes normal piece-finding and minor adjustments; excludes long breaks, filming, dismantling and modifications. Sources may use different methods. This range is neither a statistical interval nor a limit: your build may take less or more time.

How we estimate times · sources and method

The central structure, legs and accompanying vehicles use different assemblies. Vintage components are assumed complete and functional. Editorial planning ranges are roughly 65–145%, not measured averages or guaranteed limits.

Sources do not always specify the builder’s experience. The three experience bands are our editorial assessment, based on the complexity of the set and individual accounts where available.
