Here's one more shot which shows the lug work, which is nice.
Also, I've read about the Durifort tubing being "plain gauge" but how does this compare to other companies "plain gauge", for example, Peugeot? Because I just finished up a restoration of an old Peugeot UE-8, and although it had fenders and lighting attached which added weight, it was WAY heavier than this Bertin (BTW the Peugeot had all the steel bits upgraded, so it isn't a matter of the components making it heavier.)
