Motala Verkstad (English: Motala Workshop) is a decision available to 
Sweden or a Swedish-based 
Scandinavia. It requires the nation to have researched Mechanical Production and the state of Svealand (Province of Norrköping, to be precise) to have a 
Machine Parts Factory.
It raises the factory Troughput by 5% in the province of Norrköping and gives 5 Prestige to Sweden.
One might need to appoint a party with State Capitalism or Planned Economy in order to manually build a Machine parts factory. If waiting for the 
capitalists to do it, the conditions will almost never be met.
