Daz I'm sorry but I can't comment on the Seafire at the moment because the link to the pics seems to be broken.
All, I came across this item yesterday and did a jump for joy, to quote the blurb from the text "Here is the coming SH48051 Spitfire Mk.VC model in 1/48 scale. Kit will be from the galvanic form and it will be available in spring 2007. There will also be the Seafire Mk.II and Mk.III in the same scale."
I presume galvanic form is referring to some sort of low pressure injection moulding but I'm not too sure to be honest

I have been waiting for a decent Mk.Vc Spitfire for sooooo long now its ridiculous
Cheers
