All right! Those little Spits were actually completed a few days ago, but things got in the way, and I was not able to complete this thread until now... Sorry about this!
The kits were exhibited at a show in England over the past week end, so in the end, lacking the time, I decided to temporarily forget about adding details in the Belgian Spit. Indeed, I see now I took the 'final' pictures without adding the antenna wire on the Israeli aircraft and the whip antenna on the Belgian one. Apologies for this. Oh, I forgot to say that I did not use the masks provided for the painting of the canopy, finding this way too complicated to bother with...

Eduard 1/144 Spitfire Mk.IXe

Eduard 1/144 Spitfire Mk.IXe
So in conclusion,
I totally recommend this kit. Easy build, lots of possible colour schemes, relatively easy to find references, small price, two kits in a box,.. This kit has it all, or almost all. Yes, it IS a pity Eduard did not include a plastic cockpit in the form of a seat, floor, instrument panel and control column... The inside of the fuselage halves could have taken a bit of detailling too to complete this cockpit. As mentionned earlier, I have some reservations about some of the decals, in particular the deep shade of blue of the French markings, but on the plus side, the quality of those decals is really, really good. The instruction booklet is minimalistic when it comes to the actual assembly (but really, there's not that much to assemble!), but is superb when it comes to the colour schemes, with all 5 choices fully illustrated. I also think the choice of this particular variant (Mk.IXe) was a bit 'strange' for this first Spitfire kit in 1/144 from Eduard, but then the aircraft was used by the Czechoslovak Air Force. We've seen strangest choices of kits in the past from many other manufacturers.. Lastly, it is maybe also a bit regretable that Eduard did not offer separate alternative rudders, as many a Mk.IXe had the rounded one.
Let me remind you that Eduard do offer a pre-painted photo-etched fret to completely furnish the cockpit, and that the Mk.IXc variant is now also available, with a choice of 4 colour schemes. This Mk.IXc kit is a double kit too, and both fuselages feature the rounded off rudder (the ribbing of which is not totally accurate, if you are a rivet counter..).
Of interest is that the Mk.IXe was first released during e-Day 2012 without a box and with striking markings for a single Czecholsovak aircraft (different from the one featuring in the cardboard box release).
Finaly, if those markings provided by Eduard do not satisfy you, keep in mind that some manufacturers have released markings for some Mk.IX Spitfires. KitWorld, in the UK, have a sheet featuring a British Mk.IXc aircraft graced with a beautiful, barely-clad lady... JBr Decals from the Czech Republic offer two sheets, one for Israelis Mk.IXs and one for British, Dutch, Danish, Belgian, Soviet, Czechoslovak and Turkish Mk.IX c/e (some of them civilian aircraft). More will no doubt be released elsewhere in the coming months.
