This file documents the discovery, analysis and restoration of a Normandy battle field find radio rack. The radio rack most likely came from a command halftrack belonging the HQ of Panzergruppe West commanded by General Geyr from Scheppenburg. This HQ was famously attacked in an air raid at la Caine, which led to the destruction of Geyr von Schweppenburgs command vehicle. Afterwards the discarded rack must have been recovered to shore up a dug out on Hill 112, where it was re-discovered more than 70 years later in an excavated bomb crater.


This document describes the "Patin" remote compass system which became the standard aircraft compass of the German Luftwaffe in WW2. It was found in all wartime fighters like the Bf109 and Fw190 and all larger aircraft from Do17 to He177. The document charts its history, design and operation and list all known Patin indicator subtypes.


This document by fellow collector Helwig Schmied describes the restoration of a Patin PDS three axis autopilot and a number of automatic radio guidance systems: the system that couples "Y"-beam system to the autopilot; an automatic bomb release system using the "Y" system; the system that allows automatic alignment with an airfield or "Knickebein" Lorenz beam. 


This document describes the self-synchronising gyro compasses used as part of autopilot systems by the Luftwaffe. The Patin "Kurszentrales" provided a stable directional signal for the autopilot and were self contained remotely operated units that could be placed in any convinient space in the aircraft. This was a particular benefit for smaller aircraft, where space on the instrument panel was at a premium.
