Yes, I have seen the previous 6 page thread - some very good info on that thread including your Jeffery N.E Double Rifle - made by the Grandson Charles Leonard in 1939.
Great that these older N.E Double Rifles are still being used for their intended purpose, as well as the modern-built Double Rifles of Holland & Holland and Westley Richards and other Gunmakers.
