Here two more pictures of the black one.
Guess all know the story behind them and why they are in East German scabbards. A Dealer her in Germany made a deal with Vietnamese dealer and he could only get the bayonets/knives but not the complete ones. So he bought the knives and put them in his piles ...

Hello all,
have the two types of Vietnamese Bayonets for sale - 80 Euros each plus shipping - trades are also welcome, but have quite an overall types collection.
