The spitfire looked great, definitely not a disaster. The red decal things round the guns can be a pain. As a fellow Australian who lives between wheelabarrowback and the middle of nowhere, I can sympathise with your woes. That said, I still don't have to travel 800km to a model shop.
I'm actually near Coffs Harbour - so have the choice of Necastle to the south or GoldCoast/Brisbane to the north. Both are a similar distance and I haven't found anything decent any closer with my web searches.
Actually, that reminds me; the red decals are a representation of red canvas patches which were applied over the gun ports when time between sorties permitted. Don't leave them off, but if they're rough, crooked or lifting they're almost certainly plausible!
