[Seaplanes]

The RLM Lieferpläne Nr. 18 and 19 contain the following information on the Bf 109F-0 and some of the prototypes involved:
Bf 109V23 had W.Nr. 1801 and the Bf 109V24 was W.Nr. 1929.

Delivery of the F-0 series was as follows:
Total ordered 19 aircraft. Delivered up to 30.06.40 was 5 aircraft.
Up to 31.10.40 was 12 aircraft and up to 01.03.41 18 aircraft. Unfortunately I have no confirmation on the delivery of the 19th and final Bf 109F-0.

Also regarding the Bf 109F-1 series I can add the following:
Messerschmitt Regensburg had an order for totally 157 Bf 109F-1.
Up to 31.10.40 10 aircraft had been delivered. Up to 31.05.41 155 aircraft had been delivered.
The only licencee for the Bf 109F-1 was Wiener Neustadt who built a total of 49 Bf 109F-1 up to the end of May 1941.

Most of the Bf 109F-0 aircraft were delivered to Chef des Ausbildungswesens. From 14.10.40 to 29.12.40 a total of 11 aircraft had been assigned to the training establishments. The rest was probably kept for various testing purposes. On 01.03.41 the following F-models were used for testing: W.Nr. 5601, 5602, 5603, 5604, 5605, 5642, 5716 and 5717.

The first Bf 109F-1 aircraft to an operational unit was to J.G.51 at Mannheim on 19.12.40 when they received 8 aircraft. By the end of January 1941 this unit had received a total of 117 Bf 109F-1 and F-2 aircraft.
