Hi, does anyone have any knowledge, experience or information on these?I'm not even sure what to call them!

I recently purchased some wood rims from France and these are coming with them. I couldn't find a great deal of info online and was hoping someone out there may have knowledge of them.
From my limited research they are an early, pre inner tube, tyre cushioning device; or I have heard they were used during WW1, when rubber was in short supply.
I would love to know more!
More pictures to come when they actually arrive.
Thanks,
Darren.

Thanks @Rambler, I believe that's a photo from a museum in Switzerland. Would really like to find out where and when they were in production?

Hey, once you get them, let us know How they Ride......
Yeah right!
They're missing a couple of the cork segments, but I think that can be easily remedied.
Whether they're ever used in anger is another matter entirely, can't imagine fast cornering downhill with them!
Should arrive next week.

Well, they arrived today.
One is complete, in the sense that the inner steel bar is connected, the other isn't!

As delivered and unboxed.....

They're obviously not for the wood sprint rims.....

This is what I meant by not connected.....

This is how they join; the 'nut' has two flat spots for a spanner and the other end of the bar is threaded for about 1 1/2 inches......

I'm so hoping that's some lettering/logo under that crust!

Here are some shots of one of the sections of cork.....

I'll try a little gentle cleaning of the 'nut' tomorrow if I have time.

The wood rims are " Laroche Pouchois " by the way, and are true as you like, lovely.....

I cleaned up the nut section of the retaining band, discovered that the section the nut is fixed to has a left-hand thread. Nut has 4 flats, not 2 as first thought.....

Sadly no logos were found. I filled the nut with penetrating oil and left it for 3 days. Today I freed the nut and managed to attach it to the other threaded end.....

Have mounted it on this TOC French rim.....

The rim is this size and it seems to fit well.....

Will have to make at least 5 new cork segments I think.
Still searching for info?

Ok ... looks like Westwood rims made in france by the Gravigny Factory size 70 (700) and i think the 35 is the style number of the rim

Gravigny is a town located in Normandy.
Looks to have been a foundry in this town around 1900 -
a forge called Sainte-Marie, created in 1859 and bought by the S.A Gravigny in 1905. - this dates the rim approx due to the
crest of foundries Ste Marie de Gravigny, which places them between 1890 and 1910.

Many thanks @filmonger.
I've done a little sleuthing about gravigny but I hadn't come across those images before.
As an aside, the rim has pairs of holes punched in it at regular spacings around it. I wondered what these might be for but now I think they may have been a crude attempt at retaining some form of solid tyre using square section tacks/nails. All holes have been punched through from the braking surface side.....
