Working German Field Telephone FF33 – 1943, Maker Marked SA (Süddeutsche Apparate-Fabrik Dated 1943 - Feldfernsprecher 33)
 
This particular unit is in very solid condition and what makes it especially unique is that it still works! We’ve attached two external wires with clips (in a non-invasive manner) so it can be operated using a standard 4.5V flat battery. The handset, buzzer, and generator crank are fully operational – ready to send or receive a call just like it did over 80 years ago.
 
Features:
Original SA (Süddeutsche Apparate-Fabrik
Year of manufacture: 1943
Original Bakelite housing with minor wear consistent with age
Functional crank generator, buzzer, and handset
Fitted with modern clip-wires for 4.5V battery operation (no damage to the unit)
 
This is more than a collector’s item – it’s a living piece of history. Ideal for display, reenactment, or museum use.
