I'm pulling up this old thread to say that 24 mm seatposts are available on German ebay. Search "Sattelstütze 24". This guy will apparently ship to the US. Alu Patent Sattelstütze 24 mm Durchmesser * Diamant * DDR MIFA * 350 mm Länge * | eBay
I had a chrome seat post that kept sliding down.
Not a problem with this seat post.

IIRC, the seatposts supplied to the lower model Carbolite framed Peugeots in the early 80's were of the chromed steel variety with the separate similarly chromed steel clamp assembly at top. These do tend to slip down because of the smooth and hard chrome finish on it, unless you really tighten the seatpost clamp on the frame. The seatpost clamp can also take quite a bit of torque without damage and one can live with the chrome steel post, but it you are tired of cranking down hard on the seatpost clamp, an aluminum post will definitely not slip down as easily from the clamp and will usually require less torque on the seatpost frame clamp to stay put.

Um, I question whether it really need 24.0mm. Is that with or without the steel collar? You can remove that steel collar and use something larger, closer to 26.0, but perhaps a tiny bit smaller. My UO8 has a Simplex seat post I sanded down a bit, so I couldn't say whether it is exactly 26.0.

It allows you to fit a 27.2 seat post into a 26.8 ST. You can also use one to fit a Cinelli 26.4 handlebar into a 25.4 stem, but the exact 1.00mm size is hard to find.

It's kind of an anti-matter thing. Hard to explain.

Studio Brisant still offers world wide shipping via its website: studiobrisant_com (sorry can´t post a link) so maybe its ebay?
Just go to Teile > Sattelstützen or switch the layout of the site to english in the top right corner
