Jeunet models were 610, 620, 630 to equate to the Mercier 100's, 200's and 300's. I got the Jeunet numbers wrong the other day, sorry. 610's and 100's were gaspipe, 620 and 200's had only 3 main tubes 531, 630's and 300's were full 531. 630's had T/A cranks instead of the Stronglight 93's on the 300's.
At the time I thought the Mercier frames were sweeter. They had a kinda neat stay-end treatment at the dropouts and I seem to recall that the Mercier frames were pinned and silver brazed. Besides the graphics were neato.
