Gournet uses a hammer and chisel, which I feel is more appropriate for classic Parkers/Foxes etc. Wonder if the other engraver used a Airgraver? PS. Gournet has done 2 guns for me so far and another will soon enter the hopper. I also have one done by Bob Strosin which is excellent. Bob used a Airgraver far as I know. I think he is now semi-retired.
