The engraving on longrifles was done by hand and doesn't look the same as engraving done with an airgraver. I know that people use them and that's ok, but I prefer to do my engraving by hand. It took a lot of practice without any classes to do a halfway respectable job,not something you pick up overnight. So, buy a hammer and engraving chisel and maybe if your nice your friend will help you with some designs. Try to hold down the noise please.
