The Bear-Hunting Armour can be obtained from a man in Ekaterinburg if you've befriended a girl named Eija in Helsinki, who will tell you to visit him. The man will ask you to transport the item to Colombo, where it will fetch £7300. He also opens a route to Krasnovodsk in order to get started.
One route which should work for the first part from Helsinki is to Minsk > Moscow > Ekaterinburg.
The best route from Ekaterinburg might be Krasnovodsk > Merv (actually leads to Herat) > Waltair > Madras > Colombo.
