I think the one pamphlet is about the Nowill [not Nowal] Knife as John Nowill and Sons have been Sheffield, Eng knifemakers since 1700. They made straight razors, hunting knives, combat knives - all kinds. Maybe this was a sort of sales catalog. When Penn was imprisoned he wrote pamphlets about the fundamentals of Quakerism - this could be one of those - perhaps not original but a reprint. It looks like an eclectic grouping so Mitchel was interested in a range of topics and perhaps picked these up at the local 'store.' Or bought them as a lot at an estate sale! But they were cheap to buy which was part of the attraction. Liane
