These have so far received their spare parts from the corporation's central stock in Germany, but now they are considering establishing two separate stocks for serving the Norwegian market. The distances, given in nautical miles, between the different places are shown in the table below, where the places are: (1) Stav, (2) sund, (3) Ber, (4) lesund, (5) Krist, (6) Trond, (7) Bo, (8) stad, (9) Tro, (10) Hammer.
