Liebe Sammlerkollegen,
in der Zeitschrift "The Wireless Age", Ausgabe Mai 1917, fand ich folgende Werbung:
Könnte es sich hierbei um die Modelle A55 (2000 Ohm) und B55 (3000 Ohm) handeln?
Der Preis des 2000 Ohm - Typs entspricht dem im RM angegebenen. Allerdings müsste dann in beiden Fällen das Jahr korrigiert werden.
freundliche Grüße,
