SB-Zusatz FF33 telephone handle cradle by Signalapp. Fabr. Julius Kräcker AG, Berlin 1940

Nice and rare accessory for the FF33 field phone. This device was attached to the top of a FF33 and allowed the handset to be placed in the cradle, depressing the buttons and disconnecting the line. Basically turning the FF33 into a desk model. Produced by Signalapp. Fabr. Julius Kräcker AG, Berlin 1940. Very nice and hard to upgradeSB-Zusatzfor the FF33.
