Osman will run; Season 4: episode 21.

Can someone tell me , who are they talking about in this scene(nayman giving sword of Noyan to Osman), whether it’s the same Noyan of Dirils Ertugrul or someone else.
If he is that Noyan (enemy of Ertugrul) , then whether he was turk or mangol?
What history tells??? Please let me know!
