I can imagine the excitement of finding a bike in NOS condition. I have purchased a lot of components that were pushing 60 to 70 years old that were NOS and I was excited to do so.
But, the bike in question is at the low end of the scale for Peugeot in those years and as such what you have is a mediocre bike in great condition.
Someone wanting a pristine, low-end bike might pay $250.00 for it. I wouldn't.
