Hold on to your hats!!
Bachelier, very interesting. Fillet brazed. Pump pegs inside the frame. Oval rings, quick release through axles front and rear. Same housings for what appears to be sealed bearings in the b/bkt. Chainwheel inside the frame assembly. Humber did a couple of similar prototypes in the 50's in an attempt to keep the chain deflection to a minimum. Segmented fork ala Orange and segmented stays like an On One. Integral rear rack. Note how long the mudguards are. Actual date unknown. More on next page.

Best one yet.

It has five forks, effectively. This builder had some strong ideas about cycling.

C.N.C (Comptoirs National du Cycle) build and fine tuned by Ernest Czuka rando frameset. Very nice condition and a good price - if any help needed get in contact with me :)

(Not my offer! And not related to the seller)

And I must add that the frameset was discussed on the German board as well. It seems that according to a fellow over there, that the frame might have some dents...

Looking up the ‘Intégral’ derailleur featured on that bike in The Dancing Chain, there’s a bit of a photo of a very similar looking frame and the following text:
“Around 1928, the Intégral front derailleur excited interest among bicycle tourists. It was usually equipped with three chainwheels but it could have as many as five… …The bicycle itself was of an unusual experimental design, with the chainwheels inside a divided frame, and with a floating chain. It was a failure in the Chanteloup trials, but André de Boubers, president of the FFSC, used one for many years”
 
Thinking more about that amazing Bachelier (can’t stop looking at it), I’m sure I’ve seen that dropout/axle system before. If I remember correctly the wheel bearings are actually in the dropouts -giving a wide stable support of the axle, as well as being easily accessible. Ingenious engineering!
