Bf 109 G with DB 605 AS. Early deliveries were all Umbau, beginning with Erla, Antwerp. 2 in 1943 (probably Dec., none in Jan., 26 in Feb., 46 from Erla in Mar. plus 20 from RW E, 43 from Erla in Apr. plus 48 from Rw E and 5 from BV. After that the data I have is not complete. Prien and Rodeike's book is generally excellent, but I believe the C-Amt monthly reports were not in circulation when their book was written. The key is separating Neubau from Umbau as defined by the RLM. "It appears that if the conversion was done after leaving the assembly plant, then the aircraft would be considered “Umbau”. A good example is the Bf 109 G-5/R2 referred to by Rasmussen in his message of on 12 Sep 05 . These Bf 109 G-5 aircraft were apparently converted to the Bf 109 G5/R2 subtype at the Erla Antwerp repair and modification facility (no new build final assembly was done at this facility during 1944) and 34 Bf 109 Aufklarer from Erla A (Antwerp) appear in the monthly reports for Umbau aircraft for July 1944. These may have been “new” aircraft, with only test flight and ferry time from the Erla final assembly plant at Leipzig to Antwerp, but Umbau is how they were identified by the RLM."
