Another recent find is a "Empfängerprüfer für Torn.Fu. bf". This test unit was manufactured in relatively low numbers and allowed the Torn.Fu.b1 and f sets to be tested in the field. The test sets is a relatively small box that folds open to reveal a HF control, instrument, operating instructions and a storage compartment for the antenna cable. The unit itself plugs into the power and headphone socket of the Torn.fu.b1 and f transceiver, with the power supply cable coming from the battery box now plugged into the side of the test unit. An antenna cable with attached earthing wire is just long enough to reach the antenna socket and earthing boss of the transceiver. The unit provides a test signal at 3050 kHz, interestingly it does not use a quarz oscillator but a very stable RC circuit. The test unit allows the frequency scale of the receiver to the checked as well as the selectivity. Although it is called a "receiver tester", it also tests the power output of the transmitter and can be used to calibrate the frequency of the transmitter. So with the "Empfängerprüfer für Torn.Fu. bf" the Torn.fu.b1 and f could be comprehensively tested and adjusted in the field. It would have been used by a "Funkwart", a trained radio maintenance specialist who would go around the field units to test and repair their radios. regards, Funksammler

I found another bonkers accessory for the Nachrichtengerätekarren! If you mount the Rückentrage on your Nachrichtengerätekarren, the wire spools off towards the rear of the cart which is quite logical. If you want to use the cart to spool up the wire though, you have a problem as you would have to push the cart backwards to do this efficiently. No worries, the German engineers set to work and rather than simply fit another towbar attachment to the back of the cart the Germans chose to design a complicated reversal subframe. The subframe neatly slots into the attachments on the Nachrichtengerätekarren while the Rückentrage in turn is locked onto the reversal frame. Now these leather straps on the supports of the cable cart suddenly make sense, as they are used to keep the subframe secured to the cart. With the subframe fitted the cable feeds onto the Rückentrage from the front. The Rückentrage is slightly tilted backwards which makes changing the wire spools slightly easier and puts the spooling guide in the ideal position. The Rückentrage is also fitted with an additional driving gear with a handle on each side which can now easily be operated from the rear of the cart. So all in all, the subframe neatly solves a number of ergonomic issues... Although I have not found a manual describing the reversal frame, I suspect the frame and additional drive came together as a "spooling up" set. I also have not found the official name of the set and subframe, but without a doubt this was a wartime innovation. Interestingly, the backward tilt of the reversal frame was incorporated in the postwar design of the Nachrichtengerätekarren, although in the postwar design, the Rückentrage points permanently to the rear, so the card has to be pushed backwards during spooling up operations. regards, Funksammler

I would think these are not easy to come by, at least a true SAS beret that has seen action, My Brother in law worked with the SAS and was a Para and he later worked in there stores and even he could,nt get a true one, they are closely look after
