Diskussed a lot of times before. Because of several hints/proofs (eg trademark, trend to leightweight, Praxenform) these ugly hybride edged weapons were found to be post may 45 by serious and experienced collectors.
Nothing but a wishful thinking (because of ownership and money) that these hybrides could be original.
