RN Aircraft, a division of Russia's gaint Rosneft petroleum company have ordered a total of ten DHC-6-400's from Viking Air. The order was announced by Rosneft at the currently ongoing MAKS 2015 airshow in Moscow.
Deliveries of the aircraft will commence in Nov-2015 and run through Feb-2017. The aircraft will be used primarily in Russia's Krasnoyarsk region.
I would guess that MSN 928 C-GFAP which arrived unpainted in Victoria a couple days ago may be the first aircraft, given the timing of the first delivery in Nov-2015.
