Hello Gilles


From my point of view, the part is one of the early variants of the 5907 series (single needle autosyn receiver). The variants (ranging from 1 to greater than 100) differ only by the dial, the remainder of the mechanism is the same. So, the "13" variant could be an early one and, with a 360 degrees dial, this device can only be compass or direction finding related, and not necessarily standard equipment.



And datation would be more late 30's or early 40's, and a civilian origin cannot be excluded.



The part could come from a plane in difficulty throwing removable equipment...


Have a nice day !
