Remanufactured black plastic charger key. Fits most Sparklets models from around 1920 through to 1981, when Sparklets manufacturing ceased in the UK. This includes the glass bodied Types C and D, early and late Streamline models, Hostmaster Mks. 1, 2 and 3 and Aquarius models. This item features a tool to remove the neck sleeves in the Hostmaster Mk. 3; there is another slightly cheaper charger key similar to this which does not feature this tool.
