Hi Mitch,
That is looking great! I think you have the style down. Two things I discovered examining engraving on 18th century British guns is that they used a round bottomed graver to scoop out deeper relief such as the interior of a volute or curled leaf. You really see it well when looking at parts on which the engraving is worn. The other feature I've noticed that they often created deep shadow and dark relief by using a square graver and mashing it into the shadowed area not worrying much about nice parallel or neat shading lines. Once filled with dirt and gunk, it looks just as good as any banknote style shading.
Anyway, well done Mitch and I would love to see the gun those parts are for.
