I've purchased a very heavy (23lbs) beautiful flintlock bench rifle with the name "H.D. Binkley" and with no other markings. It is a .45 caliber with lots of engraved brass parts, steel engraved lock with a peep sight setup that's actually part of the tang casting. I was told by the person I got it from it was made in Germany in the 1950's. Would appreciate any help in finding out more about this nice rifle. Thanks in advance, Charles
