I think you are late to the party and just realizing this 15 years ago I went to Italy. It was explained to me by some of the biggest engraving operations and engravers how this is done and then they showed me they were using lasers and then touching it up by hand virtually everything atBottega Giovanelli in Brescia has always been some sort of mechanical engraving and very big into Laser and 99% of it isn’t even touched my hand all the Caesar guerini and Beretta‘s and Rizzini‘s or at least most of them are done there and they always list them as engraved by the master, the funniest thing to me nobody questions it. and virtually all of the Rizzini‘s and guerini are the same gun which is different level of engraving that they pay to the engraving house for mechanical engraving.
