BT-K……..I have that kit………There were no instructions but I’ve built so many Mk 1a Spitfires that I can build them blindfolded and with one hand tied behind my back…..:D
On the packaging it shows the spitfire painted blue…….but I painted mine in brown and green with the light green underside common of Mk 1 Spitfires…….
Will take some photo’s and scan them to share with you some time………..
