Nice tutorial and a nice fowler. Thanks for posting that.
Now to sum up:
MoP was not used very much on 18th and 19th century flintlock or percussion longarms in use in America, but there are some examples out there.
It will be somewhat difficult to cut easily, and it may be prone to breakage, either as you do it or afterwards. Silver or brass would probably be a better choice.
Inletting that shape will be difficult, to say the least. Many on this board have the skills to do it, but for a first gun, that design laid out on a silver/brass oval will be easier.
The taste aspect of MoP is controversial, but do what you want on your own gun.
Russ T. Frizzen is in a mood where he has insulted Joehenz, Cosmoline, LaBonte, WildEagle, and me, just for showing examples or stating that MoP was used on a number of guns. :shake: I have no (gentlemanly) reply to this at this point, except to say that he is either stealing Swampy's pain meds, or perhaps he needs to. :blah: (glad to see you're on the mend, Swampy, btw.) That will be my last reply to his personal attacks.
Do what you want - do it well, and it will usually look good. Do it badly and... you will fit right in with innumerable badly-done, cheap guns of any era. It is probably historically correct to carry something plug-ugly, either fancy or plain, as so many people seem to have done, but I wouldnt advise it.
