[Seaplanes]

I am trying to reconstruct the batches of Bf 109B-1 aircraft delivered on RLM contracts. According to Lieferplan (Production Plan) No. 8 from July 1, 1938, a total of 363 Bf 109B-1 were produced. Messerschmitt delivered 76, Erla 175 and Fieseler 90. This should be well established facts. However, when comparing my Werkenumber batches with available references, this does not correspond. My data is based on original documents from Bundesarchiv Freiburg giving details on aircraft at various repair facilities up to July 1940. My finding are as follows:
W.Nr. 286 - 416 (28 aircraft identified) W.Nr. 419 is the first in a series of Bf 109D-1 aircraft.

W.Nr. 540 - 617 (12 aircraft identified) W.Nr. 619 is the first in a series of Bf 109D-1 aircraft.

W.Nr. 1013 - 1063 (15 aircraft identified). W.Nr. 1075 is the first in a series of Bf 109E aircraft.

W.Nr. 1712 - 1718 (4 aircraft identified). W.Nr. 1723 is the first in a series of Bf 109C aircraft.

W.Nr. 3001 - 3083 (32 aircraft identified). W.Nr. 3093 is the first in a series of Bf 109D-1.
Can anyone please help me to establish the correct sequences of the Bf 109B-1 production batches.
