| Description |
Älteste Ausführung mit zylinderförmiger Anode die allerdings auch nicht ganz geschlossen ist. Diese Ausführung gab es mit Metall- und danach mit Bakelitsockel. Einige Exemplare mit RTV-Banderole deuten auf einen Produktionsbeginn um 1924/25 hin. Die jüngere Ausführung mit U-förmiger Anode wiegt nur noch 32g. Die Abmaße sind fast identisch.
