Waste of time. In that "collection" only the popular daggers seem to be real. All the chained ones etc. are copies. The so called "NSKOV dagger" which is nothing more than regular SA with NSKOV badge attached to the scabbard. You can see a dagger like that in Hartung's little catalogue which is really poor reference. This way some people think such model of dagger really existed and stick the NSKOV badges to the scabbards to raise the value
