The Quest resolved!

Vallter: We have received more than 800 e-mails with answers. But only 64 users filled in the questionnaire correctly. And only 7 of them, who were the fastest, will receive the prizes:
Xerxes17
Elenar
Belrick
Urbanowicz
TheMagister
Mastertaco
nut123456789
And now the correct answers on the questions:
1)VK 3001 (H)
2)The 12 has been changed to 52. The author is doel89 (the bird was a tip, that images were posted in our Twitter channel)
3)Christie Suspension System
4)Sydney Valpy Radley-Walters (born 1920)
But the same image on the European and Russian Wiki was for Pierre Billote (born 1906). And it supposed to be this tank ace. Now there is a correct (or none) image.
We beg our pardon for this technical inconvenience. Because of it the password for the next task was posted in the first message of the quest topic. But still you had to send us the name of the tank ace in the final questionnaire. We accepted both answers, Pierre Billote and Sydney Valpy Radley-Walters.
5)SU-76, SU-76M and Ferdinand. Mentioning two of three TD's guaranteed you the correct answer.
6)No, it was not mass produced.
And SerB is the Product Manager (WoT Producer) in the Wargaming.net Company.
What will be changed in the next quest?
1) We will try to integrate the quests into our portal functionality.
2) Number of questions will be increased. Difficulty of the questions will be increased.
3) The quantity of winners will be increased.
4) The Quest duration will be decreased.
5) The photo with SerB will be substituted -)
