Extremely hard to find 'little known facts' about the Ford Model A, Henry Ford and the Ford manufacturing. More is known about this model, its production and its maker - than any other machine in history.
But for 10 to 15 minutes of 'Over view' just about ANY book or article about Henry Ford and his (Edsel's) Model A, will do.
You could tell, for example, how the Model A was meant to be a temporary 'band aid' to hold 'market share' while the end of the 19 year run of the Model T was replaced by the Ford V-8, which was not quite ready when the "T" production ended. The Model A was never meant to replace the Model T. The V-8 was meant to replace the Model T - it just was not quite ready and had to have a few more years to 'work out the bugs' of the revolutionary V-8 engine.
For the short time allotted (10 minutes) you really only have time for one topic/subject. As has been suggested earlier - a quick GOOGLE SEARCH will be the easiest and quickest.
