ANY INFO ON CAST ALUMINUM(?) RUSSIAN HEADS/BUSTS?

I found these at a local thrift store today. Are they anything special?
Are they made of aluminum - or pot metal?
Are the names on each the person or the artist?
I am pretty sure larger one was a Russian leader, but who? And who is the young soldier?
Any info would be appreciated!

 

Here is rest of young soldier

 

Does it look like they may have been painted with silver paint, like something a previous owner might have done?

 

Lenin, I think, but would have to check.

Edit: No, wrong beard. Could be an anonymous officer to go with the anonymous youth. The name on the soldier strikes me as being that of the artist.
Edit: Wrong again.

 

Matrosov.

boy those did not travel well........I suggest painting them again..

 

Best I could fix.............

 

Could it be this man, Russian revolutionary Dzerzhinsky?

 

The larger one is "Klyu**kin" or Klyu**kim". Can't quite make out the middle letter/s

 

I think you may be right. A Google search on Dzerzhinsky metal bust brings up many that facially resemble him, including the clothing. Not sure if this search result will work in a link:

If it is him, that means the name on the back would be the company who made it. (EDIT: it is the sculptor's name, as April07 says in the next post.)

 

Клюшкин - Oleg Kliushkin is the name of the sculptor.
Here is a similar bust, and it's identified as Dzerdzhinsky https://antik-group.ru/magazin-2/product/byust-dzerzhinskogo-f-e
The material is silumin

 

Yes, I think it is him looking at all the pics. @journeymagazine hasn’t come back about the identification as yet.

 

Thanks for the info, I hadn’t heard of Silumin, I know silicon is added to bronze to make it flow better when casting.

 

That's it!
Never heard of silumin either.
So is this a real sculpture made by him - instead of 1 of many made by machine?
Thank you all - you guys are as amazing as ever!

 

It could have been cast from his model any number of times. Depends on what you mean by 'real sculpture.'

 

1. First one is Felix Dzerzhinsky (Феликс Дзержинский) was a Bolshevik revolutionary and official. Known as "Iron Felix'.
2.The small one is Alexander Matrosov ( Алекса́ндр Матросов)
was a Soviet soldier during the Second World War, awarded the title of the Hero of the Soviet Union for blocking a German machine-gun with his body.

 

Thanks Max Levy!
