what year would serial number f9780A (I think it is a lower case "f")have been made?

Maybe the script prefix is not an "f" as this gun has a waafenampt.

Prefix letters used on SN were upper case.
Yours looks like a C to me, in which case the year of built is 1943.

The mle 1935 A pistols built under German control (WAA251) were mostly allocated to the their medical staff in France and also to the French police.

Here is another view:

The prefix letter is indeed a "C", made in the last quarter of 1943.
