Probably false memory syndrome but I definitely remember one of the Eduard kits came with two fuselages and wing sets. Which one was it? I want one, if only so I have a spare when doing the cutting to do an Fw 190C!
You want either the Royal Boxing or the Dual Boxing. If I were you go for the Dual Boxing as you get four different Fuselage/Wing sprues rather than three in the Royal box.

I had an A-5/A-8 green hearts dual combo boxing which gave you four sets of wings and four fuselages to build two aircraft.
