After some reading around the various options I have narrowed down the next Bag the Hun scenario project to the Norwegian Campaign and the Franco Thai War. The Norwegian option looked good on paper but had less going for it once I dug a little deeper, with the Norwegian Gladiators wiped out in a single day of fighting and the RAF really only engaged in the air defence of Narvik and some attacks on shipping, with a distinct lack of much dogfighting. 

It’s still worth a look, perhaps as a basis for two or three scenarios on the ‚Last Stand of the Gladiators‘, so I’ll save that one for later and push on to research the Franco Thai option instead, at least for the moment. I haven’t abandoned the other ideas either but need to find a lot more background material for Syria, for example, before making any scenario outline sketches. Thanks to everyone who has offered their ideas, as it’s always useful to have a second opinion.
