Good stuff so far. It's a nice kit, despite a couple of minor errors - I've got 5 of them to build for my BoB collection, along with another 3 from Hobbycraft and Tamiya.
Note that, if you're building the E4 versions, the canopy has been modelled from the RAF Museum example, which was restored using a canopy from a 'G' or 'Buchon'. Therefore, the centre frames need to be removed.
