Stephan, thanks for the reply.
I did check out the forum before the buy and mine looks like the one on the left (the good one).
There is one other forum link, where they mention four things to look for.
1. both stamps (most common both on the side of the clip, but I have seen other for sale , wih stamps on the side of scabbard, as said I have not seen any with the stamps at different sides).
2. soldering on the rings
3. "D" styled holes.
4. spacing on the center ring / connection at scabbard.
All 4 are ok !
Plus the dagger is 100% real and fits perfect into the scabbard.
If I was not for 100% sure then I would not have bought this dagger. Also the story (history) explains a lot. See next post.
Only thing that is not so clear on my pictures are the "D" style holes. But in real they have the flat base,the appear more rounded but that due to wear and age coloring.

this picture below shows what I mean, the left has a nice "D" shaped hole, the right ONE gives the impression to be a round hole (due to wear/dirt) but it is a "D" aswell.
