i don't have the blueprints for the build weeks - and only seen 1 example of an F build week. PY member has a 64 or 65 or 66 A body with an F build week.
The old crash box has a picture of it saved... iirc
Wish i could just remember the month and year
So only 1 known exception to your graph Ransom.
Not bad at all for a PMD factoid !
