The using a links between a frog and bayonet is very problematic, i could remove a frog from bayonet in 10 second and give them other piece on. Similar is to see as Your 41ddl piece have a frog with added DH? but the other SS piece have a normal Wehrmacht kvz piece. The tracing of originality of complete bayonet-frog, after 70 years is very hard, only some attic founds could be to 90% declared that they are so from war. For 100% is for me not real.
