    No idea. It's a nice object though. How old is it, 30s?

    Yes, 30's would be about right.

    Aah, yes the 1930's - height of the marble playing era.

    Not telescopes. Ophthalmic as in spectacles.

    Hope so. Somebody needing a size 13 bridge would have one hell of a conk.

    I think maybe the photo is deceptive, if that is diameter in mm. But it could be radius?

    Close enough Bobbygloss. :D
    It's for checking the diameter of the crest of the bridge of a spectacle frame, when comfort was more important than style!

    Over to you Bobbygloss.

    I think you gave it away, saying it was for glasses and we'd already had the gauge for the lenses.
    Anyway, need a new image quickly, before the marbles start.

    About half a metre long without hoses.

    Some sort of pipe cleaning or checking device?

    Pipe, yes. Cleaning or checking, no.

    Does it go into a pipe and then seal it off? It looks like the rubber bits on either side inflate.

    Think I went there in 1983.

    The number of bolts in the plates suggests it's fairly high pressure. Hydraulic press?
    Sometimes parts break. Sometimes you crash. Sometimes it’s your fault.

    Yes, and they do inflate. Sealing for a specific purpose.

    The rubber parts take a reasonable pressure, 90 bar or so. But most of the strength is required for removal.

    Is it used to seal and cap off live pipelines?

    Sorry, missed this one. Can you explain?

    Basically you put 2 short pipes end to end into a junction box, this is then charged with electricity which melts the ends and fuses them together, so you get 1 long pipe

    Seems I was wrong. I've never seen one but it's what my imagination thought it would look like. Wikipedia says otherwise.

    Rubber bits inflate and seal either end, stuff is sucked out if the gap in the middle so the pipe can be repaired by welding, brazing or whatever? Don't know what you'd call such a contraption.

    You'd call that contraption a welding pig, which is what this is. This one is for new pipeline fabrication, it purges the central part with inert gas so you can weld stainless steel without getting oxidation of the weld root.

    You're up.

    Right apologies but this is the best I can do right now. Would have been better if I was at work but I'm going in late tomorrow. Try this, the yellow thing as the cork is for scale.
