Clark--I'm gratified that you find the book useful. My main goal in writing the book and incorporating so many detailed photographs and descriptions was to get info out there concerning these muskets, that had not been discussed in other books or lightly touched upon at best.
Man at Arms Magazine just published Part III of my Springfield Armory Musket Evolution series. I have one more article in the que but it pertains to the Allin Conversions not my main obsession, flint muskets.
If you have any questions please do not hesitate to e-mail me.
