LEGO prototype parts

Introduction

Here is an overview of our rare and unique LEGO prototypes.
Prototypes are parts that have never appeared in any sets, or have appeared in sets, but there are differences from the released version.
To see released parts in special colours you can choose test parts in the navigation menu above. Click on a picture to find more information on the prototype on Flickr.

We have been lucky to acquire some very rare and special prototype parts over the years. Like the Seatron minifigure, space turbine and castle walls. Nearly all the parts have been found in Denmark, from various people sorting lots and stumbling upon these parts. One day it would have been fun to find some more history together with them. Sadly this is often lost as the parts and collections have moved hands many times.

Any extras we have will eventually be added to the shop.
