Hello ClinA-78

What you found is a „Reparaturschild an DB-Motoren“ (repair-plate on DB engines) which was introduced with Anweisung des Technischen Außendienstes Nr. 11/43 from March 1943. The Reparaturschild was to document the current technical condition of an engine in a prominent place und replaced the former yellow and red painted triangles or similar markings.

The upper, smaller column is for Grund- or Teilüberholungen (major or partly overhaul). On your engine the first row has a “G” for “Grundüberholung” and “3606” as a code for the repair-facility. Perhaps some Engine-buffs can tell us, what this was. Alterations done by Daimler-Benz Außendienst would have a “TA” in this place. The second row should have the flying-hours, but for some unknown reason is empty (as you did not find any other parts of an aircraft, this engine perhaps was an replacement-engine with "Zero" flying hours". The last row shows “244” for February 1944.

The lower, larger column documents what Änderungsanweisungen (instructions for alteration) were incorporated into the engine. Here first row is for the number of the RLM-Änderungsanweisung, second row the code of the repair-facility and third row again month and year.
On your engine ÄA (Änderungsanweisung) 101 was done at repairwork “3606” in February 1944 and the same with ÄA 187. Some other ÄA were not carried out, perhaps the engine had this alterations already incorporated when finished at the original manufacturer.
