This is an ultra sought after original WECO tube, with the lower side "D" getter, and top wire spring supported filiament!  Over  52 years old.....  definately the real McCoy. It tests very strong on both calibrated testers ... the TV7 it measures 54/55  (min 40) and the Jackson at full load reads 115%/115% (min 70% -- Guaranteed NO DOA.  Both testers indicate a very well matched tube with little or NO use and a VERY long life ahead. Will provide the sound and excellent lifespan you can rely only on very old WECO tubes for.   Single "d" getter tubes were only made from the late 40's/50's til early 1960s...an excellent era for top quality. Western Electric tubes like this will outlast and sound much more detailed many of their similarly designed counterparts  (like mil spec 5Z3 / 5u4G) ... upgraded your rectifier results ( surprisingly ) with amazingly improved  resolution & musicality.... as noted by many advanced listeners in Asia/USA.  This old tube has been carefully stored for years in it's original Western Electric box which shows some wear/stains from storage.
