Possibly 1942, serila number suggests so, but frame build looks like late 30's. A load of very fancy stuff on it, including a "unknown" Italai (French, says Bte SGDG) derailleur working on the Oscar Egg principle of shifter fork and chain tensionner, but much more complex as regards the movement of the shifter fork, which slants up/down as you move up or down the three cogs.

Left for the time being "in it's juice" as the French expression goes. Meaning fully disassembled, but no repaint and very litle polish. However, a load of oil rubbed in to keep things stable. Kind of a "museum piece" more than a rider. For the moment, anyway.
