I'm not trying to be a smart ass about this but honestly, there are any number of good books with fine pictures of traditional engraving and carving. When I was building rifles in the 1970's I used existing antique rifles as a template. I would copy a maker's style and in many cases, especially engraving I would copy the original makers engraving patterns.
There are also good books on the art of engraving that will teach you how to sharpen a graver and how to create different effects in your engraving.
Perhaps I'm unclear as to what exactly you want to see from us?
