    Something of a collection of parts rather than 'as it left the factory'

    'As it left the factory' + 69 years

    Now, the AGM fuel tank has become the windscreen ...

    1338934309-2.JPG

    ... and a brass, somewhat dented, Coleman fuel tank dated 1945 replaces the AGM tank

    1338934317-3.JPG


    The AGM fuel tank was full of rust pin-holes. I've chopped it up here ...

    1338934335-4.JPG

    ... to reveal one of the larger piercings on the outer rim of the generator mounting boss

    1338934345-5.JPG


    Along with such corrosion were gummed-up components ...

    ... and just this component I could retrieve from the non-return valve

    1338934390-10.JPG


    Here was a dilemma. I had a Coleman tank that takes this type of NRV and locking rod ...

    1338934401-11.JPG

    ... and the AGM NRV locking arrangement is a different pattern, with the AGM valve bulkier, so even if I could have removed it from the AGM tank (I couldn't) it wouldn't have fit the Coleman tank.

    The solution was an adaptation of the Coleman NRV and locking arrangement to make it compatible with the AGM pump

    Back to that windshield made of some sheet steel retrieved from the AGM fuel tank.

    The stove came to me without a windshield and though I at first thought of making one up out of sheet brass to match the Coleman fuel tank, I decided to incorporate a memento of the AGM tank and brazed up a cylinder from a portion with the 'US 1943 AMERICAN' legend on it.

    Here's the windshield already having been silbrazed up from sheet and ready to silbraze onto the burner flame plate lugs

    1338934431-14.JPG


    Complete and cleaned up

    1338934443-15.JPG


    Fuel/air stem, generator, burner bell and windshield ready to instal in the fuel tank

    1338934458-16.JPG


    Before firing up the completed project, I reminded myself how it should look fired up by giving my Coleman 520 a test firing

    1338934476-17.JPG


    The 'mostly' AGM fired up fine, the orange flame here settling down to a proper blue colour after a while

    Next job's to make up a set of those pot rest 'fingers'

    A very good fettle indeed. What a gunked up fuel pick up tube but I was confident you'd sort that one out :thumbup: Congratulations!

    Very nice and creative.

    And it reminds me to light up one of of my WWII era stoves tonight in remembrance of D-day.
