    While cleaning an old vaporiser if found one that has a patent number...

    Is it special or noteworthy in any way? I don't want to sell it and I'm not asking if it's valuable, I just want to know if it's worth keeping. It's pretty badly wrecked inside and the jet is elarged so it's unusable.

    I have a project in mind for it but it would mean destroying it. I thought I'd ask first before I do anything.

    Hum.. interesting..

    I don’t recall that knurling being that common?

    Was it on a lantern or spares?

    That's the first version of the vapourizer, made before 1946. By '46 they had changed to straight knurling with the patent number stamped horizontally, rather than vertically, then sometime in the '60s they dropped the patent marking.

    By his book, and thus according to Ian Ashton, this patent about a spring inside the vaporiser to guide the needle was published on 10.07.41 .
    No idea how long such patents would prevent copying, and thus would be stamped on the relative item not beyond the date of expiry of such patent.
