Grandma had a shortwave, young'un .... Tubes... 'ya know ??? ;^)

Seriously... identifying a germanium diode by the glass case is
a big mistake. Lots of silicon diodes have identical cases... especially 
those from the same era of manufacture.

Look for voltage drop. Some meters will identify this with a diode test 
(Fluke for instance) Germanium is about .3V, silicon about .7V

Schottky diodes will meter low also... maybe .4V
