If you buy Skorpion G twice do you get the gold?

I have the 30% off coupon for playing WoT for 5 years, so I am thinking of buying the Ultimate offer for the Skorpion G even though I already have the Skorpion G. This is because it is worth 10900 gold and so I'm basically paying £35 for 18k gold and some other stuff. My question is, do you actually get the gold if you buy a tank again from the premium shop and also do the missions (5x exp for win) start to work for my currently owned Skorpion G or they do they not work?
