An unknown mark ... can anyone help?

[Ed]

It is on a Luger pistol. It is fairly unique.

The Cyrillic reversed N suggests a connection to Russia, the crown pre revolution. This mark might be on a sword or other bladed weapon.

I am at a loss, any info or notions appreciated.

A similar pistol generated some controversy over on Still’s forum.
