Roden has put out at least four issues of the Beechcraft Staggerwing. I'm just wondering if they all have exactly the same sprue in the box with decals being the only difference, or is there sprue changes?

Excepting the floats on version 4, of course.

Thanks

If you look over at the Roden section of the Reviews page you will find reviews of all 4 boxings.
UC-43
Traveller II/GB-2
D-17S
SD-17S
These reviews will tell you that yes, the plastic is the same for all 4 releases (except for those floats)

Thankyou, Jessica. I have the GB-2, and would prefer to do it in civilian colors. Knowing so little about the Staggerwing, I wasn't sure if there were significant differences.
