Tested Matched Pair of Hammond 12AU7 Tubes.
These were originally made by GE and rebranded for Hammond Organ.

Tubes are closely matched for mutual conductance (Gm) and internal structure - they are identical.

The wording on one is partially worn away while on the other, the wording is mostly worn away - see photos.

Tested on a calibrated Hickok TV-10 military tube tester with no shorts and no leaks with the following results:

Gm Test = 2350-2450 and 2300-2400 micromhos
Minimum pass/good = 1400-1400
