Those wings look a bit short to me...

Indeed!!

I might have guessed you two would come up with something on those lines.

Just for once I'll stay with the standard length, but I have at least 3 or 4 more Mirage F1 kits in The Loft...……..

<....> They also include some resin wingtip missile rails, but why I have no idea as there are no less than FOUR styrene wingtip rails included on the main sprues, and they're better than the resin ones. 
The resin parts are for the Spanish marking option. The Spaniards used Sidewinders instead of Magics, hence the need for different rails.
<...> four piece ejection seat (Why?) and it's a different seat to the front one too, very odd. <...>
To make it detailed?
I think the front seat has canopy breaker "horns" because of the curvature of the canopy. If the MDC didn't shatter the canopy, the pilot's helmet would hit the canopy before his seat's headrest would. Not good.
For the backseater, that's less of a problem as his seat's headrest would probably hit the canopy before his helmet does.
Ahah, thanks for that, although I always thought that 'winders and Magics could be fired from the same rails.
The 'breaker horns' make sense, yes, but they could have moulded them in one piece, they're not that complex when they're assembled. They do look very good though.
