First time poster on this forum. I have had a couple NSKK daggers in my collection for some years now. I am researching the maker, a Peter Lungstrass of Solingen-Ohligs. I have tried using the search engine to learn more on this maker but nothing more than his assigned RZM M7/57 designation.

Can anyone provided rarity scale on this maker and current market value? The Gau mark is "He". I will also post a few photos showing this dagger. All comments are welcomed.

Oh... the other NSKK dagger is maker Malsch & Ambronn Steinbach with Gau mark of "Th".

Thanks
