re: visser collection
it is part 3 but not really a swords book, focused on dutch 17th and 18th century weapons such as smallswords, hunting hangers, walloon swords etc.
re: Oakeshott
I think Oakeshoot meant the same, a Dutch Swedish broadsword from around 1650 but probably by some similarity in the form of the quillons , naming the type sinclair 2.0
