A printing code stamped on many Marklin boxes helps reveal the production date of the box and thus allows for accurate dating of Marklin articles. Sometimes the prices marked on the boxes and referencing pricelists also approximately dates an item because prices often changed from year to year.

W. Seelig LTD of Great Britain, London's leading sales organisation (according to their company) distributed Marklin toys to hardware stores and toy shops all across the British Isles. To promote their Marklin products, they created the "Marklin Expert Library of Handbooks" which we will review in this episode.

Innovation in 1938 and the introduction of the "Perfect Reverse" system brought many changes to the Marklin product line not to mention the 800-Series line which would last several decades. Unfortunately many of these innovations and even those that were planned but never came to light were halted due to the onset of WWII.

Despite intense turmoil in the European continent which could be felt all around the world, Märklin survived the Second World War with its business relatively intact and ready for explosive growth in the post-war years. In this episode we'll look at the compromises and advancements Märklin made during this time.
