I am hoping to do a 1/48 Spitfire Mk.Vb to Mk.I with cannons (aka Mk.Ib) conversion - preferably using an Airfix kit as I believe that the kit fuselage is more accurate than that for the Tamiya version. Your opinions on this issue would be greatly appreciated. I suspect that the Cutting Edge gunsight might also be a problem - the words "rocking horse" and "droppings" come to mind. Any tips, hints and pointers would be welcome. Cheers John
