this is a till know realy "unknown" dreyse needle fire stalking rifle model here SN 5617 and made around 1865. it is never described in gun literature and not mentioned in old books anywhere. I know 4 rifles ( two rifles can be seen in the thread) of this typ in 0,60" and 0,49" where the rifle in 0,60" probably shoots the prussian military cartridge.
this excellent pics coming from kudua and showing the action in detail. the rifle is chambered for a paper cartridge with 0,49"(12,81m) Zündspiegel - means the rolled paper sabot. the bullet was maybe in the 11-11,5mm range. the gun came from the estate of Prince Heinrich von Preussen, brother of Kaiser Willy and born in 1862.
