A wonderful "Zimmer - Stutzen " , or parlour rifle , circa 1880. These were small calibre , extremely accurate rifles for indoor target shooting , essentially the precursor of 10m air rifle matches . This one worked by placing a percussion cap on the nipple exposed by an aperture under the barrel and pushing a 4.3mm lead ball down from the muzzle , no powder being required . The nipple is hit by an inline striker , attached to an external hammer , actuated by double set match triggers . When the gun is cocked , pulling the rear trigger "sets" the mechanism so that only the lightest touch on the front trigger will fire the gun . Excellent condition and perfect working order , with micro rifled bore , adjustable match peep sight , lovely walnut stock and steel furniture , with much original finish . A fine quality and fascinating thing and great value at £795 , posted UK .
