C. Lorenz A.G. was since May 1930 owned by I.T. & T (I.T.T.) also sometimes called Standard Electric. After the war, the company was known as: SEL, which stood for: Standard Electric Lorenz (Standard Elektrik). Late 1980 sold off to the French company Alcatel. 

Rather curiously, in Radio Mentor 7/8 of 1943 the receiver being described inclusive a full electrical schematic. This might point at the fact that this receiver was originally designed for a commercial purpose, and it was then purchased by the GAF.

In post war days this receiver type was found in use by several services, also, for instance, within the French Armed Forces, but also at DPA and Norddeich Radio.

Its performance is quite good, although, the employed quartz-filter is performing inferior compared to the Telefunken Kauter type, like was used within the E52.. series, Main and Wupper, not to forget the MWE-c! The latter being a very compact, but marvellously performing receiver.

However, it took me > 30 years of waiting before I got a complete set again. My first set was obtained in the early 1970s (Otto Guhl), then a second one from Ebbe Petersen, however the latter lacking its box (housing). Both were, for what ever reasons, swopped and the one without case I could repurchase about 2010.

For those interesting in its military manual: D.(Luft) T. 4415

Apparently, there is quite some dust at the front panel.

The Al box designated QF 1 is the tuneable quartz filter

Viewing the right-hand side into the power supply module, like almost every Lorenz RX this set is also fit with semiconductor rectifiers

Side view of the box (case)

Always attracting me, as these lids give access to the 11 RV12P2000 valves.

Apparently, someone has 'modified' the mains (interconnection) plug. Genuinely, it is having an ugly KM naval plug. This modification allows the application of plugs used for Köln E 52 and its derivates and many other systems too. This type can even today be purchased, at least in Holland and Germany.
