Hi Both,
Thanks for your data. Mick, your 3rd set suggests that the move to the separate Hacker badge happened before the addition of the DC socket, which I *think* arrived at around 30000.
Ron - thank you. Did you know that your set has the wrong scale? Yours should be all white - I've got several with lower serial numbers than yours that are white. Having said that, I rather like the white and green version
Incidentally, have any of you got a Royal Warrant? Personally, I have a feeling the warrant was added when they changed the model to "Hunter fm/am" - if you're adding a warrant to your scale, you might as well have a re-brand while you're at it! But that's just a theory at this stage.
Thanks,
Mark
