Here is a list of all large model LEGO sets sold in the 1971-79 era... and where they were sold under which number. (from Chapter 9 of my collectors guide - LEGO Model Sets 1971-79)...

One of the more interesting sets was the 340 Train Control Tower Set of 1968. This set came in several box types, 2 of which are shown here. The box on the left shows the box for continental Europe, without writing on the box top. The box on the right shows the USA Samsonite LEGO box, with "Model Maker" on the box top. Here is one of the strangest LEGO sets ever produced. From 1970-75 Minitalia sets were produced for the Italian market. These sets were produced because in 1970 the Italian Parliament forbade the importation of construction toys, for some strange reason. The blast doors on the front of the shield generator bunker cannot be opened together. They are opened separately by different cogs. Also, the exploding armour-plated walls on the sides of the building cannot be launched off, but still can be removed. Parts 60896, 60990, 60935, 62386, 64251, 64330, 87794, and 87807 are unavailable and have been left out of the model. The pilot is therefore not buildable, and all of his parts have been left to the side. The fire sword (part 32588) cannot be dual-colored on LDD. It is supposed to be co-injected with 21 Bright Red and 191 Flame Yellowish Orange plastic. It has instead simply been colored 21 Bright Red.

The Midak Skyblaster piece is not available on LDD and has been left out of the model. The four Zamor spheres have been left to the side of the model.

In 2014 TLG will introduce the 10241 MAERSK LINE TRIPLE-E SHIP with the color "medium azure"... as the new LEGO color for Maersk models. This is a sad farewell for Maersk blue, a (until 2004) very rare to come by LEGO color.. which appears to have been retired as a color in 2011 (with the end of production of the Maersk train). LEGO boxes produced in the Czech Republic/Hungary sets produced for Europe generally have somewhat different printing on them than do those produced in Mexico for the North American market. This difference has often been the case, and in some decades past, there were even greater differences between boxes. During the late 1960s it was even likely that the sets themselves contained some different parts on both sides of the Atlantic. During the 1970s the same sets produced for the USA market even had different set numbers, than those produced for other countries. And even sets produced for the LEGO licensee (Samsonite for USA/Canada, Courtauld's (British LEGO Ltd.) for UK, Ireland, Australia) had different box types. The USA sets of the 1970s and 1980s had English writing, while the European/Australia versions came without writing (except mainly to list the ages of play for children, in different languages), since they were for countries covering many languages.This set came in 2 different box designs... the older 1966-67 box (top image), and the later 1968-70 box image (middle and bottom image). The top image is older because it shows prototype gas pumps, which are unknown in any collection.
