Today we have a J. Gumpf Kentucky rifle for sale. This rifle looks to have been produced by Jacob Gumpf as indicated by the the engraving on the top of the octagonal barrel "J + Gumpf". The Gumpf's were a well known family of gunsmiths based out of Lancaster, Pennsylvania. This rifle has been converted from the original flintlock configuration to percussion cap ignition. The estimated age of this rifle is sometime between 1814-1847. Chambered for what looks like .42 caliber (measured several times to get the most accurate reading). This rifle is in fantastic condition for the age! The stock on this firearm is in amazing condition. There are some nicks and small dents, but no cracks. The finish is in great shape. The brass pieces have some patina to them, but are in great shape as well. The fine line engravings are very crisp. On the left side of the buttstock a brass leaf with some mid-ribbing is present along with a brass diamond. There is a small ridge that runs underneath the the leaf and diamond and is intended as a cheek rest and is in prefect shape. The trigger guard does have a break on the edge under the double triggers. Both triggers and hammer function perfectly. The bolts and screws used in this weapon are in great shape. The underside of the buttstock seems to show a little wear possible from where it has been hung on the wall and placed on the ground. The butt plate seems to have a small ding on the top edge, but once again nothing serious. The bluing on the gun is in 90% condition. There is some minor pitting around the rear of the barrel and receiver. Definitely not serious. The scrolling on the on the receiver and hammer are in great shape. The hammer has a little more wear than the receiver, but both are in good shape. The receiver has a very clear "Dreppert". The outside of the barrel is in good shape with a little finish wear around the outside edge of the crown. The interior of the barrel seems to have minimal wear from corrosion or blackpowder residue. The front sight has some finish wear but is still serviceable. The rear sight is in serviceable shape as well. There are two crests, one in front of and one behind the rear sight. They are a little difficult to make out, but they are there. This firearm has the wooden ramrod that sits perfectly into the stock. The brass muzzle cap is in great shape. There are pictures of every inch of this rifle, so give them a look through and if you still have any questions let us know.
