I cannot tell you how glad I was to see these great images of the gun arrow and the other items!
Thank you so much, and don't worry about the quality of the photos; I am very familiar with the horribly dim light conditions in the Nuremberg museum displays both in the Kaiserburg (Imperial Castle) and the GNM, and I think you did a fantastic job!
Thanks also for confirming that it actually was a gun arrow! As I wrote, a friend of mine and me spied this important item in the drawer of the reserve collection at the GNM about 15 years ago at a meeting of the Gesellschaft für Waffen- und Kostümkunde
; at that time, the rear end still retained a small portion of a cord binding which is now sadly gone!
I will ask my experienced friend Ralf, who collects Gothic crossbows and accouterments, about your query concerning the 'nutfingers'. Please allow one or two weeks; as a consequence of his profession, he has to travel a lot, and his spare time is precious.
Diy you take photos of the crossbows in the museum of Sibiu/Hermannstadt, Romania? The local female curator did not allow me to do so because she was still working for her dissertation on those cossbows about three years ago.
With all my very best wishes,
