As you will be aware you shouldn't be seeing those numbers from a Ge diode so the first thing to do is to try another one. You could use a B-C or B-E junction from a Ge transistor as in the original design if you have something handy - the exact type shouldn't matter much. It would be prudent to test before use of course.

Cheapo radios made at that time often used transistors as diodes so the marketing people could increase the claimed transistor count, which was a selling point. They sometimes used reject or marginal transistors so they are always worth checking.
