You are buying a Sylvania Type 47 tube. This was tested using my recently refurbished and calibrated TV-7 Tube Tester. Testing - Minimum Acceptance @65 % is 50. This tube tested at 66. NOS is considered 76. So this tube tested very good to strong. Tube was tested for shorts, gas, and mutual conductance.
