Hi Michl,
This is absolutely one of my favourite muskets whitin your timeline display at your home. That combined system of flint and matchlock and the story that goes with it are just sublime.
One wonders where the at least 19 other muskets are? Would all the bodyguards (a loose translation on the Leibgarde) be equipped with the same ingenius gun?
Are there any records from the Von Stauffenberg armory about the way they came to posses this gun? And where the montecuccoli muskets in the possession of the bodyguards up until the death of Raimundo or only during his campaigns (like those in the Netherlands)

.
The striking steel of the flintlock pan (frizzen) is original and without a repair (like so many other flintlock's which have been repaired with a new piece of hardened iron), so would these guns ever been (actively) used?
A lot of impossible questions, i am sorry
You would have made a frightening Leibgarde yourself if the pictures tell the tale (post 10)
The website on the Gesellschaft für historische Waffen- und Kostümkunde is very interesting. They too like the Vikings seeing as they have a correct!!! Ulfberht sword at there homepage. Would they also accept foreign members, it looks like an interesting and serious group of scholars.
