Look like fantasy pieces to me. Way more of that floating around than legit WW2 Germany relics.
My dad came hoe from WWIi with all sorts of nazi memorabilia, including Mein Kaumpf, a Luger, a few K98k’s and a few brand new uniforms, helmets, w/ insignia. Does that make him a nazi or a sympathizer...No, it made him a collector of the things that had a major on him as a young adult.
To some degree, if this were the former belongings of a high ranking nazi, They too would be just as susceptible to keeping things from their prior lives that they figured might have some residual value in the future.
