Well the Breeze isn't really worth much of anything, its a mass produced 3spd with an Archer Sturmey 3spd setup... my mom had a purple one many years ago. Its kind of a cool bike but is too common and not unique/innovative/rare/interesting enough to really be worth a whole lot.
And about the Flandria from Sheldon Brown, a guru of anything bike related:
"...actually Belgian, not French. Most Flandrias seen in the U.S. were low end bike-boom clunkers, some of them made in Portugal."
So the Flandria probably isn't worth much either sorry to say. You can always fix them up and ride them, but I wouldn't put much into them personally, unless they have sentimental value.
