Ah, so it is an earlier version.
Well, it IS but the timescale for the Mossies development was comparatively short. Looking down the production history, many variations were produced in 1942/early 43 and it looked like a case of 'can we make it do that'? so they tried it. There are a variety of noses, nacelles, bomb bay doors.. even tail plane widths so to nail one down as the definitive Mossie isn't easy
What usually happens is that model development starts and we get a first version to play with. Anything obviously wrong is reported and this gets fixed. This process goes on until we arrive at final beta. Final beta is 'pre-release' and if that's ok.. it gets released. With the Mossie, we had a beta 6 years ago so what Dave has done is gather all the bits together and bolt them up. None of us are sure where the previous/first beta was at.. it's too long ago so for that reason, it's being 'rushed through' if I can put it that way

Everything that should work
will work but the main emphasis is getting it into the public domain in it's current condition rather than rivet counting
Art.. sri mate but I can't really recommend any of the available Mossies as I doubt I've tried them. The last model I flew was the first beta of this one and as you know, that was 6 years ago and I can't remember that far back
