Since a few weeks I am busy collecting photo material for Technic Set history. This is a very interesting action. going through the history of Lego Technic. I do have already this idea for a longer time to collect all technic Lego sets and put them in a picture collection. Currently I finished the 70-ties and 80-ties.
With this collection/way of representation you should be able to filter on type of set like farm, car or race or filter by year. Currently you can do that via menu 'Pages' and select either 'Technic Sets' or 'Set Time Line'. I only concentrate on sets or idea books so no educational sets or replacement part sets.
