I came across a web site that shows the 15 engravers that work at the Gebruder Merkel gun factory in Suhl Germany. Their experience ranges from 6 months to 41 years. Note the vises they use. None of them have a self centering vise like the Italians use nor do they use an engravers block like most of us use. Also their vise is on the side of a bench not on a corner or on a post. They do great work but use an H&C method many of us would consider a handicap because of the vise.
Here is a link to their engravings pages. The pictures are not high resolution but you can get some idea of the work.
