Russ,
The thing I am questioning (genuinely questioning, seeking to learn I might add) is the sharp distinction you are making between the terms "rifled musket" and "rifle musket" as it seems to me that in original sources such as the two I linked to, "rifled musket" is a term used to refer to weapons which never existed as a smoothbore. Or at least as far as I can tell.
It is obvious to anyone who reads here however that I am a neophyte at this compared to you, especially in your knowledge of specific weapons, their manufacture, their refitting, etc. But I direct you to my first
link from a previous post which is to the 1861 manual of arms by E.E. Ellsworth entitled:
"The zouave drill: Being a complete manual of arms for the use of the rifled musket, with either the percussion cap, or Maynard primer . Containing also the complete manual of the sword and sabre"
My presupposition is that people living in the time period in question (especially people like E.E. Ellsworth who set about the task of producing manuals of arms for the military) would use the correct terms for those arms.
Since the Maynard primer is mentioned in the title in connection with rifled muskets, if your thesis is correct, then there ought to be some citation somewhere to smoothbored muskets equipped with the Maynard primer which were also rifled sometime in the course of their service. If such a citation can be found (and I will look tomorrow), then I will concede the point to you, and to your obvious knowledge of the subject at hand. If no such citation can be found, then it leaves us with three options.
1) The terms "rifled-musket" and "rifle-musket" were used interchangeably, thus demonstrating that at least in the minds of the people in the time period, "musket" did not mean "smoothbore".
2) E.E. Ellsworth used the terms incorrectly.
3) That some smoothbored muskets were rifled which either had been, or were subsequently equipped with the Maynard priming system, for which we can find no historical records.
In any case, as so often happens in historical study, it is exceedingly difficult to find a "smoking gun" (if you will allow the play on words) which can determine the point with absolute certainty. The best you can do sometimes is to ascertain a high or low degree of historical probability. Depending on what we find out about my previous query, I will leave it up to the readers of this forum to determine for themselves the degrees of probabilities for the various possible conclusions.
In any case, soon I will stop :dead: :hatsoff:
