Never saw a miniature proof eagle on an original MP-40 muzzle nut, but the seller of the one pictured below claims it's original. I'd thought that the only things proof marked on an MP-40 were the barrels, receivers, and bolts. What do you think?
Also, the original nuts I've seen had slightly chamfered edges, apparently so that they didn't quickly wear the retaining wire clip.
