I had a modern tester that was totally incapable on old germanium transistors, giving all manner of strange results. Luckily I do have a tester from the days of germanium and it works a treat. There is a warning in it's instructions about results and these indicated that a high hfe reading with high leakage was a problem.
To quote: "Low duty transistors which simultaneously have a great back current (Icb > 5 uA) and great gain factor (B > 150) in most cases cannot be used for practical purposes."
Whether or how this may apply here I don't know.
