I did a small bit of research on your question and came across this title: "Rules for the Management and Cleaning of the Rifle Musket, Model 1863 for the use of Soldiers with Descriptive Plates." It's available as a reprint of some re-enacting supply sites. I found this on
www.fcsutler.com though I'm sure it's available on other sites, and you might be able to find a copy in some libraries, especially university or state archive libraries. This is a book CW soliders would have used. I don't know if this helps, but thought I'd post just in case.
