If my memory serves me right, the Jacques Anquetil brand was sold by mail-order, probably Cyclo-Pedia, in the late 60s and early 70s. The Huret Allvit rear derailleur puts it right in this time period. The Allvit didn't shift as well a the Simplex Prestige, but it didn't break when you fell on it (it bent instead). The geometry, steel cottered cranks, stamped dropouts, cover plate over the fork crown, and Mafac Racer brakes suggest that the model you have is a "campus tourer," comparable to a Raleigh Record or Peugeot UO-8 of that period. These were made of chromoly steel, with seamless main tubes and seamed where you might not notice--usually the fork blades and steerer.
The top of the Anquetil line was comparable to the Peugot PX-10. By the early 70s demand for Peugeots was raising the price, so you could order one of these for a bit less.
With new tubes, tires, handlebar tape, brake pads and cables, and a chain, it might bring 10 bucks at a church rummage sale. Or you can ride it around town and be assured that no one will put too much effort into stealing it, like I did with the old Peugeot that I got for free.
No, I mean someone dropped off an old Peugeot at the church rummage sale. No one bought it because it was unrideable. I took it home, put about $35 into making it rideable, and we ride it. I'd seen far nicer bikes languish for less money.

It's not worth rebuilding anyway unless you have a cheap strategy for upgrading the rear hub. I get 500 miles tops out of those before the wheel starts to wobble and bearing balls break in half.
