I must confess, I was always impressed at how Peugeot had the sheer brass to just pop those dubois lugs outta the box and braze 'em up. Files? We don' need no steekin' files!

compare to early an Gran Criterium, or the white Pogliaghi just on ebay (very cool bike, btw).
Peugeot did make some very nicely-finished pro frames around this time, or, really a few years later, but you had to special-order them. Not many like that were made, from what I've seen. But the couple I have seen are very tasty.
This PY10, by contrast, is pretty crude.
