Herman,
is the double oval you are showing etched as well? I have only seen that maker mark stamped on HJs, and I have never seen the etched original 35-41 mark. Since the later 1942s are stamped, why would some early versions be etched? Makes me worry about a post war embellishment, especially since the 35-41 etched with motto you are showing appears to have been buffed quite a bit.

Just thinking out loud, John
