Picked up this old H. Burgsmuller & Sohne topped with a Hensoldt-Wetzlar 2 3/4x scope I think is an 8mm, however it is not stamped in the barrel. Tried to research it but coming up empty. I have only found it is from Germany around the turn of the century. The action looks Mauser with a hexagon barrel for about 10 inches from action then goes round. The sight rail is like the Dan Wesson pistols. It also has two triggers. Anyone know anything about these or what it may be worth?
