Three kits in one. You have the choice of 3 versions. I chose the one from sq 487. Pro's The kit had no fit problems. Instructions very clear. You just have to choose which version you want to build before you start. Nice detail in the cockpit and landing gear. Nice panel lines on wings and fuselage. Con's The only thing I found I didn't like was the option of the open window on the canopy. I thought I had it glued on even. But after I glued it on the fuselage, I noticed a small gap on that side. I didn't double check how it fit on the fuselage. It will need to be sanded down just a small bit. I liked it so much am getting ready to build the B MK.IV bomber. (Item 60753)
