Huge sword - Persia or Caucasus

[wolviex]

Rivkin - thank you very much for your efforts, I really appreciate it!

Does Armenian letters excludes Persia as a place of workmanship?

I don't know if these (a little bigger) picture will help:

The problem is, this is only a part of the blade. The letters are barely visible and it's a real pain taking them with camera.

Thanks!
