Hello Mahdi!
It's my pleasure to be able to help you a little bit. I remember that you were the first person out of Ukraine from who I bought awards when I started to collect in 2001-2002. I remember it was the most common jubilee medals but you were very kind with me and contributed to make me addicted! I am happy to see you are back on the forum.
It's pretty late and I am supposed to be sleeping already, but I found a bit of info for you that I wanted to share.
His full name is: Челноков, Николай Васильевич
Chelnokov, Nikolai Vassilievich
According to
Warheroes (which seems to be offline at the moment!), his HSU number are:
1- 14.06.1942 ( medal № 653)
2- 19.08.1944 ( medal № 24, second award)
He is one of only 5 navy pilot to have been decorated with two HSU gold star medal:
259 Fleet aviators were decorated with the Hero of the Soviet Union award while 5 of them – A.E. Mazurenko, V.I. Rakov, B.F. Safonov, N.G. Steranyan and N.V. Chelnokov were decorated twice.

Maybe later, their website will be up again, but until that time, you can access the cached version which is not too bad!
Hope that's all you needed.
