Markings on a Takouba-mounted European Backsword

[blue lander]

Hi,

I posted this on the ethnographic side, but as the blade appears to be European I've started a thread on this end.

The blade only has two markings on it. One is the writing, apparently in cyrillic or a related alphabet. The other is two clusters of three dots. There was probably something in between the dots, but corrosion removed it.

Any thoughts on what the blade says or where it came from?
