It is interesting how they made the Hooper body work with the dash. Not typical Springfield you are right. Definitely need to know the full history before spending any money. Very possible those fenders were done in the 30s when skirting became a way to update the styling. Typically open fender cars with skirts added never look great (see 17" wheel Duesenberg for example).
I do like the Hooper coachwork. Something different than the typical Brewster bodies, although I like those too.
