Russian 6x5 Plumb?, No Numbers

[LanceF250]

I've been wanting to add a Russian 6x5 to the collection for some time now. the few I have had the opportunity to purchase have been horribly overpriced. my patience finally paid off last week when I stumbled upon this example at a very reasonable price. better yet, it turns out to have a plum color when viewed in daylight!

No serial number on the bayonet or scabbard.

Black pebble grain leather hanger.

Blade marked OTK 51

Opposite side marked 4 within a rectangle

Pommel marked 9-1

Since this is my first Russian 6x5, i only have a Black Bulgarian Circle 10 to compare colors.
