CJO,
The Model 42 in question was definitely not engraved by Rudolph J. Kornbrath.
It was, however engraved by a very skilled engraver, most likely in the late 20th century, up to the present. The complete lack or progression marks in the cuts of the scrollwork indicate to me that the graver was powered by a pneumatic hand piece rather than a hammer.
I have an idea of who engraved the gun but I would like to see a close up of the engraver's mark or initials.
Apparently, you (CJO) are an engraver since the gun is pictured in an engraver's block. Would you mind telling us who you are?
Cheers,
Roger
