Sam is here but I don't claim to be a Kornbrath expert though he has been my engraving "hero" for nearly 50 (gulp) years now. I have seen a number of guns he engraved I would not have guessed were his work, based on photos in the Gun Engraving Review book so I never place any confidence in my own opinion of whether he engraved a piece or not.

That being said, I don't recall seeing that much English influence in his work.

Have you looked for hidden signature or initials?
