Hi 'Nando,
Please don't be too angry with me ...
I never meant any embarrassment on any side, just wished to state the Prussian origin of this lock mechanism. Now it's my turn to bow down in the face of the amount of facts presented by you - so sorry again, and congrats on your being so widely read.
Thank you so much for enlightening such a narrow-minded old matchlock fool like your Bavarian friend.
Best,
Michl
