One rare, tested new B65 (6SN7) branded Mullard, but it was actually made by GEC/Marconi, as evident by the unmistakable shape of the inverted cup getter. This is the coated glass version.
Printing on the tube is excellent. On a TV-7 D/U, where the minimum acceptable reading is 50 and new tubes usually test at 90 or higher, this tube tested new at 95/98.
