Can anyone find any reason not to buy this Nahkampfmesser?

[Axium]

I've got a good deal on a german Nahkampfmesser, its marked //5\\ or something similar. i've seen a genuine with /6\ in a book on these, but wanted to ask here just in case. I definetely think its the real deal.

The seller clearly didn't hide anyting, seems to know his stuff, and is easy to communicate with. no red flags as far as i see.

what should it be worth in western europe? 50 euro's, 100 maybe?

These can be marked with a Luft. 5, Luft 6, S, W, and a few other marks.
I can see no reason not to purchase this example other than condition.
A few of mine.

My accumulated wealth after just 30 years is also not in perfect condition, more stuff and still not rich, just missing closet space so i can live with some patina.

any guesses on the worth?
