Raimey,
Back at the top, I don't think "Omnibus" has anything to do with driving a bus, the word means "over all", "universal", or "all knowing". Back at the bottom, even today blackpowder shooters put their cases in a cleaning solution right away, and they don't have to contend with brass destroying mercuric primers like they did in the old days. Different advice on cleaning is common even today (the more things change, the more they stay the same). "Schritten" does mean steps, but we would more than likely translate it to "paces". BTW, good show on your translations.
