Still in the Prien and Rodeike's work the WNr. 5628 is listed as F-1. There are a couple of pictures of the machine, one said to be taken in october 1940 where the Messer is still with its Stammkennzeichen SG+GW, just arrived to the Stab/JG 51.
They dismiss the F-0 issue with "there was presumably a small F-0 series", and according to them, the first loss of a Friedrick (a F-1) occurred on Nov 11 1940, when WNr 5635, flown by the Staffelkapitan of 1./JG51, Oblt. G. Claus failed to return from a sortie off the English coast.
