    An early incarnation of the Optimus '0' with small bore all-through pump tube assembly. I don't know whether documentation exists as to when the Optimus model '0'was first introduced, but this example can't be much earlier than c. 1912. There is no 'patent' reference in the tank top legends such as an earlier dated example would have had. The pump rod assembly is the post-1908 type, and, compared to this earlier date example of the equivalent Optimus No.1, this '0' features the later relief-molded air release screw, not the earlier incuse marked version. On the other hand these 'later' components still sit in combination with an earlier type filler cap when compared to this just a little later example of a No.1.

    No flame shot above; I was still resigned to having to commence a long, long, process of struggling to get the NRV out. These NRVs are amongst the worst of the worst to extract if they are stuck. The only access is to the single screw driver slot on the outer end of the spring cover (or valve socket as the 1915 catalogue called it). Any damage to that and you really are in big trouble:evil:!

    But overnight, after another 24 hours of soaking in PlusGas, a miracle has occurred! The NRV has freed up and is now functioning without any dismantling being necessary:D/

    And so, barring one minor glitch/conflagration of which there will be no more said, here we go with the 1st tea test:

    Hi Ian @igh371 . What a lovely stove, and a great survivor at well over 100 years old.
    Thanks for posting.
    Best Regards,
    George.

    Can hardly believe the lucky break with the NRV on this little Optimus!
    Still really struggling to sort out major problems with a same design NRV on a similar age Record stove.
