one of the early bolt action hunting rifles, which cartridge is still unknown but I suspect it shoot the common military paper cartridge. I see it made in the middle of the 1860s.

Frame, bolt handle, buttplate, escutcheons, ornate patch box, and trigger guard are all soft gray (silver plate?) with good quality period scroll engraving. Barrel marked 'v. Dreyske. Sommerda.'; right side frame 'Cal. d. Zdsn. 0.60'-5/24 Pulv.' Horn flared nose cap and trigger guard extension. Sound full length stock shows usage marks and sharp checkering; raised relief mock ramrod channel rib on underside of stock. Double set trigger.

to bad the seller did everything to hide the SN while making such good pics. the center fire extrator and the slimmed action will place it probably in 18883-1885 as earliest time but the additional disc's on the breech end were seen late around 1890.
with the old style needle fire triggers one of the transition guns.
very unusual is the cartridge designation " Pappcart: Cal: 16 " means probably "Pappcarton"(modern german Pappkarton) or in english cardboard so its chambered for the common 16 ga. paper shell.
