To be honest Rob,
I wasn't expecting much ''umph'' from that kit anyway, it was 62 years old and sadly time caught up with it VERY rapidly. Airfix though unlike the Spitfire Mk.I/Mk.V which was re-tooled in the 1970's had much better duration before the original Mk.I was retired in 2009, but strangely the Mk.V still soldiers on as the Starter Set and can be found on shelves today.
I still don't understand why Airfix didn't re-tool the Mk.IX in that period... instead the tool got weaker, more malformed and finally killed off in 2005 before the new Mk.IX was issued in 2009/2010 which was so desperately needed and well.. we got it!
It's a wonder as to why the old tool carried on for such a long time? Everyone knew it was bad and often many modellers wrote to Airfix even as far back as the 1990's to withdraw it! Granted I was too young so I couldn't voice such an opinion back in that period.
Ah well, the kit's gone in the bin and it makes me kind of sad... because she was my first model kit and something told me in the end it wasn't worth it and focus on builds like the Ju-87, Ju-88 and modern Hurricane toolings... and well you saw the result... prop fell off, the paint wouldn't apply and well she used up a lot of my liquid poly so it wasn't worth the 3 days I wasted on it.
