The high back P-51 was my first foray into 1/72 'plastic surgery', and it may be time for another. I came across an old Revell/Monogram P-51B kit at a semi-LHS last weekend for 3.99 USD, and a similarly low priced Airfix P-51D, and decided I should attempt a hybrid suggested by @Bedders in his own Hasegawa/KP hybrid P-51B thread.
You may be wondering what's wrong with just building a P-51B from the Monogram kit itself, and the answer is: nothing at all - one of the best builds I've ever seen was from the Monogram kit. The main reason for this attempt is that I think it will be fun, and correct a few shape issues with the Revell/Monogram fuselage along the way.
