Hello KrisJG3,

#1 is a plate showing the alterations done to the engine. IIRC this was introduced in early 1944 to have this information readily available for the technicans, even if the paperwork for the engine (Lebenslaufakte) was not at hand.

At the top there is something like a header showing three major times of building/overhauling. Following is detailed information.The first row each shows the number of the alteration done ("Änderungsanweisung"), the second row is a marker for the plant doing the alteration and the last row is the time the job was done in M JJ-format. Specialist on engines perhaps can tell us, were and what exactly was changed on this engine.

So this engine is a DB605A1 built in Feb 1943 (?), had a major overhaul with a lot of alterations in Apr 1944 and was last worked on in Sept 1944.
BTW: Isn't this the engine attached to the Bf109 in Australia?

Plate #4 is from a DB605B1, so not from a Bf109 but pres. from a Bf110.

HTH
