And once more my heartfelt thanks go to you, Marcus! 
 
   
 
Sectioning that weapon among 'miniature weapons' is not tricky but simply wrong as this of course is 
not a miniature weapon but an absolutely correct and full-size, fine and extremely rare gilt-etched combined wheellock pistol and horseman's hammer, Nuremberg, ca. 1550-55 (Czerny's  labeled it as 'late 16th c.')!  
 
   
 
Best,
Michael
