Where can I find Helios Cond C and Helios Cond Black C fonts?

Question

Fonts

Hello Toasters, I really need your help. There is such a font as Helios Cond C and Helios Cond Black C , it is used in Gazprom letterheads. And it is with the letter C that I need them. So I rummaged through the entire Internet almost, but everywhere there are only Helios Cond and Helios Cond Bold, and those that I need, well, I can’t do it.
I would be very grateful if you could help me find it. Just need to give the order, I can not fit.

Answer 2

Is it Cyrillic? C is probably Cyrillic, isn't it? Those that were found, without C - do not fit why? Is the style different or not in Cyrillic?
This one doesn't fit? you-want.ru/fonts/font-5893.html
