(The tires were on the rims when I bought them. They will be replaced.)
Re brakes, my bike came with Dia-Compe NGC500, labeled 47mm-57mm reach.
I love everything about my two 710-framed bikes (1977 & 1982) except this ONE THING: clearance at the rear brake. It makes a 700x32 pretty tight at the rear (but it fits) and it's giving you different front / rear brake reach.
According to the engineer's drawing we shouldn't have this problem: the front and rear axle-to-brake-mount distance should be the same at 36.5cm. Instead, the rear bridge is 35.5cm, which accounts for the 10mm difference in brake clearance and tight fitting tires.
