Picked this up for very short $. I do not usually collect foreign bayonets but the price seemed right. Have no idea what it is other than WW2 from the date "1941".
Next time, I suggest using an electrolysis bath to clean up these old treasures. There is no abrading or 'polishing' of the metal from this process and it will clean those recesses you can't reach by wire wheel or other mechanical means. It's also a lot easier... hook it up and walk away.
