This is a rare post-WWII East German military field telephone 10 line switch board set with several accessories for display.

The desk phone has added reproduction plates found on German desk phones, and it is connected to an original German WWII battery box which is Waffenamt-stamped.\u003c\/p\u003e\n\u003cp\u003eThere are also some small spare bits and pieces, this set certainly came from someone who was trying to get the set working again.\u003c\/p\u003e\n\u003cp\u003eA lovely switchboard and phone set, perfect for re-enacting or for a German WWII display.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKleiner Klappenschrank zu 10 Leitungen 10 line switchboard\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe redesign of equipment in 1933 had the aim to simplify and the new 10 line field switchboard would be as simple as possible, omitting buzzers, alarm bells, built-in telephone and provisions to connect to public networks. These functions would have to be taken up by external accessories where necessary. At the same time the unit was redesigned for “single interconnection cord” operation, negating the need for separate interconnection cable indicator flaps. Instead of eight cables, the unit now has 10 interconnection cables, one for each line. The basic design with a falling indicator flap, interconnection button and interconnection cable socket for each of the ten lines remained unchanged.\u003c\/p\u003e\n\u003cp\u003eTo operate the new “Kleiner Klappenschrank zu 10 Leitungen”, an external FF 33 field telephone would have to be connected. If connections to public networks were required, an “Amtszusatz” or public network connection unit would be required. The redesign resulted in a unit roughly half the size and weight of the old OB 17 model. The unit did not require any presetting of jumpers or interconnections, making it far simpler to operate. A metal lid protecting the top and the use of the standard FF 33 carrying strap allowed the switchboard to be carried in the field and protected it from the weather.\u003c\/p\u003e\n\u003cp\u003eTwo locks on the side allow the unit to be opened, giving access to the interconnection cable storage compartment. Also in this compartment is a 30 pole plug socket, which can connect the switchboard to a remote line terminal unit, negating the need to connect the lines directly to the switchboard.\u003c\/p\u003e\n\u003cp\u003eNormally the incoming telephone lines are connected to the terminals on the top panel. Apart from line connections, the top panel has two terminals to connect a FF 33 field telephone and three terminals to connect an external alarm battery and alarm bell. These are all the connections that the operator had to deal with.\u003c\/p\u003e\n\u003cp\u003eWhen an incoming call is received the signal flap of the relevant line will drop, revealing the number of the line behind the flap. Press the connection button for the relevant line and speak to the caller via the handset of the FF 33 field telephone (remembering to depress the microphone switch in the handset while talking). When the caller has indicated which line he wants to speak to, press the connection button for that line and turn the generator handle of the field telephone. When the call is answered, place the interconnection cord of the caller into the interconnection plug socket of the outgoing line. Return the signal flap of the caller in the up position and press the red connection release button on top. The call is now connected.\u003c\/p\u003e\n\u003cp\u003eAt the end of the call, one of the callers will turn the generator rank, resulting in the signal flap of the incoming line to drop. The operator can now remove the interconnection cord of that line and replace it in its storage socket. Close the signal flap to reset the switchboard for the next call. Conference calls can be made by repeating the connection process: the interconnection cable of caller 1 is plugged into the interconnection plug socket of caller 2; the interconnection cable of caller 2 is plugged into the socket of caller 3 etc. In theory, all ten lines can be connected to a single conference.\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":43733540143173,"sku":"ONJR25SEAM34","price":895.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/files\/ONJR25SEAM34__01.jpg?v=1759432040","url":"https:\/\/www.ima-usa.com\/products\/original-east-german-post-wwii-field-telephone-klappenschrank-10-line-phone-switchboard-set-with-dial-box-reproduction-ringer-box-czech-desk-phone-for-display-identical-to-wwii-german","provider":"International Military Antiques","version":"1.0","type":"link"}
