    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.

    I believe that you are correct. I have heard the same thing, that cork inserts were used to replace inner tubes during wartime when rubber was in short supply.

    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?

    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.

    From what I've seen and read online the word amazing doesn't do it justice.

    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..... WP_20171120_17_09_21_Pro.jpg

    They're obviously not for the wood sprint rims.....
    WP_20171120_17_09_49_Pro.jpg

    This is what I meant by not connected..... WP_20171120_17_40_18_Pro.jpg
    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...... WP_20171120_17_45_03_Pro.jpg
    I'm so hoping that's some lettering/logo under that crust! WP_20171120_17_40_18_Pro.jpg

    Here are some shots of one of the sections of cork..... WP_20171120_17_45_41_Pro.jpg WP_20171120_17_45_56_Pro.jpg WP_20171120_17_46_05_Pro.jpg

    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.....

    Any ideas yet anyone?

    Not exactly the same - though slightly related. From the Wheel 1898.

    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..... WP_20171125_10_36_52_Pro.jpg
    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..... WP_20171125_10_43_07_Pro.jpg
    Have mounted it on this TOC French rim..... WP_20171125_10_43_44_Pro.jpg
    The rim is this size and it seems to fit well..... WP_20171125_10_44_19_Pro.jpg
    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..... WP_20171125_21_53_54_Pro.jpg
