Description

Reading the name

The title brings two ideas together. The Vault is the widely known name of the company archive in Billund, where examples of sets from across its history are kept. Memory Lane, as in a trip down memory lane, points to nostalgia and looking back. The combination suggests a model built around the past, though the catalogue itself says little beyond the basic facts. This page therefore focuses on what can be stated with confidence: the pieces, the figures and the colours.

Size and structure

The 1,243 pieces cover 228 distinct part types, so each element appears a little over five times on average. That is a comfortable middle ground, with enough repetition for a steady build and enough variety to keep things interesting. Eight minifigures give the model a lived-in feel and are a respectable number for a special edition. If you are considering a second-hand copy, confirm that all eight are included, as figures are frequently separated from the rest of a set.

A neutral palette

Light Bluish Grey, White, Tan and Black are the dominant colours. It is a calm, understated mix that sits easily alongside other models on a shelf. From a reuse point of view, grey and tan are among the most versatile colours you can own, useful for buildings, streets and landscapes alike, while white and black provide clean contrast. Anyone who likes designing their own creations will find this inventory a practical addition to a growing collection of parts.

Tools on this page

Special editions are often poorly documented, which makes a complete inventory especially valuable. The parts list below shows every element with its colour, so you can check a copy or source missing pieces one by one. The What can I build? feature compares the set with others and shows which ones you could rebuild in full or in part from the same pieces, giving the model a second purpose once its time on display is over.
