Hello John,
First, I say you have a fantastic collection, I am envious.
I do not say it is a copy but it is not the same etch as in Wayens book.motivet are etched into the blade and not on the subject, see photos and read text in Wayens book.
Perhaps they've made 2 different versions!?
I have one similar to that in wayens book, got it from an old boy in Wustrow. It surprised me that within about 1-2 years I have seen the virson 5-6 times? and I have collected for over 30 years and have never seen them before now?
Perhaps Wayen has an opinion here?

Best,Jack
