Kriegsverdiensrkreuz II klasse. Authentic?
Hello all. Tempted by a small lot containing, among other things, this KVK. I have been looking through several posts on the subject, and dont see anything wrong with it. But I have no experiense with these, so I would greatly appreciate any help. No makers mark. The following envelope marked as per picture. Thank you for your time guys.

It looks fine to me. No issues with the cross or ribbon from these images. The packet looks OK but the 'mit Schwerten' line looks like a later stamp? The ink looks darker.
I don't know if they were just printed with Kriegsverdienstkreuz 2. Klasse as a generic envelope and the swords designation added.
You might want to try searching for similar packets by Steinhauer & Lück and see if you can see if this is a common thing.

I agree with Adrian.
It all looks good and original to me, the only thing questionable is the added "with swords" on the envelope.
