It looks like I found the answer, though nothing is broken down by year here in this wartime 1939-1945 production listing. The Anglia figure does tally up with the wartime portion of one set of figures I have for this model (October 1939 through August 1941). Another source is at variance (surprise, surprise) and shows the Anglia going till June 1942 (and the Prefect till February 1942). The "Model 61" must in fact be Model 62. I knew this model was still in limited production till 1941, but had no figures before now. The WOA1 figure is the most interesting. This should actually be called a staff car and not utility car; the utility was the WOA2. With the figure from this source, and the year-range from Dymock, we can say 1,623 WOA1 and WOA1A (6.50-16 instead of 9.00-13 tires) were built from 1941 to 1944.
As for the WOA2 and WOA2A, 11,754 were built from 1941 to 1947, according to Vanderveen's Historic Military Vehicles Directory and Dymock's Ford in Britain File. The 9,059 total for this utility according to the attached document only refers to wartime production of this model, which according to Vanderveen's The Observer's Fighting Vehicles Directory, was in wartime production from May 1941 to July 1944. It must have resumed production after the war and been made till 1947.
