Hi Dmitry,
The Puype book is a paperback, so shouldnt be too bad once you find it. If Amazon doesnt have it...try Ken Trotman in England. Mr. Brown there is amazing at finding books.
The late Nick Norman and Puype apparantly worked together on things a lot as they wrote a brilliant article together for the Arms Society in London on a 10th Hussars sabre. Mr. Normans fantastic volume on smallswords and rapiers is a virtual goldmine of footnotes, references and bibliography as well.
The Aylward book is indeed one of the venerable and fantastic references of European arms collecting, again, the footnotes alone are absolute treasure. The book has been reprinted several times from the 1945 original, so does turn up occasionally...again Trotman would be a good source.
I have heard of the Visser collection, but have not seen this catalogue. This would likely be in the holdings of museums like the Higgins, and it might be worthwhile to contact them just to see of it could be viewed at thier library. I have often used interlibrary loan to borrow hard to find books, and simply gleaned pertinant data in notes and essentially copies (for scholarly use only of course) which became part of my working library until I could find a permanent copy. Obviously an expensive multi volume set like this is most likely among reference holdings so not lent out, but just suggesting the method.
Again, bibliographies, interlibrary loan, footnotes......all these are the building blocks for useful reference libraries
and served me well through many years.
All the very best,
Jim
