Your mention of Jean made a couple of neurons fire in my brain. Finally, the answer to the question: "what do the numbers on the Lygie headbadge refer to?"
Jean Valjean's prisoner number!
(Note: make sure you don't put a space in Jean's last name. Google will come up with something completely different than you were looking for...)

Listen here, young whipper snapper, I've got some alternative facts on this.
24601 + 9430 = 34031
That leaves us 5018 short of 39049 (the mysterious Lygie number)
50-18 was an optimal cruising gear in the french countryside.

Interesting, I don't seem to have that number on my headbadge.

Where did @Andy Antipas acquire this? And how does @Andy_K come into the picture (other than being over Under and under Done).
I hate to drag this back to bike components, but I'm beginning to wonder about 650B. Jan Heine seems to have done such a great job convincing us all that wider tires are the way to go, that there don't seem to be any ~33mm wide 650B tires out there any more — or at least, I can't find them. 42–44mm widths, in contrast, are now easy to find! There a more tire options in 26", but 26" wheels are probably asking for too much brake reach.

Parimotos are available in 38 width which would work nicely, and much less expensive than the Compass models
Gran Bois Lierre 36 widths are still around.
Say, I know a guy with a spare set of wheels to try different tires out before you make the plunge...

I bought the Lygie as a complete bike on eBay. I bought it for the parts and thought about building it, but decided to trade it along with another frame to Gugie for a Urago frame that Andy K had. There was another frame involved, but I don't remember the details anymore?

I spent some time this evening gently straightening the Lygie. The rear dropouts are now around 129mm, and more importantly, more closely centered around the seat tube. The fork is still somewhat off, but I'm working on it.
It occurred to me that I could try the experiment of fitting a 26" wheel because I have one — albeit with a 135mm hub. The required brake reach (to the brake track on a VO Diagonale Rim) is 75.5mm This is do-able with a RAID brake. The clearance from my 41.5mm Naches Pass tire to the brake bridge is 23mm; a 650B rim has a radius that is 12mm larger, so it seems to me that a 650B tire would have to be significantly smaller to work with a "garde-boue".
I clearly need to take up @gugie's offer of trying some wheels before I commit.

There are photos on Flickr — my Flickr handle is "Professor Squire", and the album is called "Lygie Build". Maybe one day BikeForums will let me edit this post and add the URL.

There is still moderate support for ISO 590 and ISO 597 sizes.
If you keep your eyes open, you might find some narrower 650b tires.

Oh, and this one, 36mm.
https://www.ebay.com/itm/Grand-Bois-...c/292810731234
There is also supposed to be a Grand Bois Cypres (or Cypress) 650B x 32mm tire, but I'm having troubles locating them.
It may be these are NOS tires, and reasonable to stock up if you choose an uncommon size.

Is your BB height enough to use 26" wheels? If so, that sounds like a better way to go.

Choosing a wheel size
The cranks came off without trouble, with the right extractor. The Bottom Bracket is in fair shape too – I wonder if someone needs a French-threaded Stronglight square taper? What ball bearing size would that use?

When I said “26”, I was thinking ISO 559. I hadn’t even thought about bottom bracket height. I seems that the right thing to do would be to bring the frame back to Atelier Guglielmana and try a couple of wheel sizes, measuring the necessary brake reach at the same time.
He'll be brazing on new canti posts and cable stops.

I might need his fork-bending jig, though.
The cranks are looking good:
If you are wondering why there is a pedal tap in the picture, it’s because it turns out that these cranks
Later Correction: the cranks turned out to have the French 14 mm x 1.25mm pitch pedal threading.

Thats a risk I’m willing to take. Guglie had the opportunity to do all sorts of work on this frame while he owned it, but passed it up. Even though he’s twice my height, I think that I can fend him off.

If you are wondering why there is a pedal tap in the picture, it’s because it turns out that these cranks have ½” pedal threads. I’ve started another thread in the Bicycle Mechanics sub-forum on the topic of drilling and tapping them to 9/16”.

Are you sure it was drilled 1/2"? French pedal threads BITD were 14mm, easy to tap them out to 9/16".
Congrats on getting to enough posts for picture posting!

As a comparison, my Atlantis (with the same wheels) measures 247mm; it was designed for 26" wheels. My road bike is around 255mm.
So, with 26" wheels and skinnier tires, say 36mm, the center to ground distance for the Lygie would be about 250mm. How does that seem?

I think that the answer is "maybe". I just tried 26" wheels with 41mm Compass tires, and measured the BB height. This is from the bottom of the BB shell to the ground: I got 236mm. Add around 21mm for the center-to-ground distance, which I think is how it's usually quoted.

I've been busy collecting parts. The cranks are sorted, and I've some new TA rings (26T and 42T) for them. I may be short a chainring bolt, but I think that I have one in my spare parts box (from back in the the day...) that is probably the right size. I've just bough some RAID brakes on eBay, which are on their way from Lyon — not clear when I'll see them here!
I have a Suntour front derrailure, and a variety of rears that I'll try ... hard to know which will have enough capacity until I try. Have 'bars and stem. Still need a 26.6 seatpost. Just ordered a longer BB from Velo Orange — I got the 110mm, but it's too short. I have a nice VO front cable stop, but realized after I bought it that I don't have enough stack height to use it. I planned to switch to a VO hanger that can go above the headset locknut, but they are out of the shims. Hopefully, they will be back in stock by the time the brakes arrive.
I plan to order some decals from Velocals, but I'm bewildered by the choice of styles. 1mil Vinyl with clear-coat over the top seems to be the way to go. Opinions?
The biggest outstanding item is wheels. I figure that I can borrow some 650Bs, and ride the bike with my existing 26" wheels, before I take the plunge on those.

I spied a pair of Shimano 600 "tricolor" hubs a a local shop yesterday. I'm thinking of lacing them to 650B Pacenti Brevet Rims. But it turns out that the rims are available right now only in 28h and 36h, while these hubs are 32h. Any suggestions for an alternate rim?
