I believe the RAF 48 in the plans are plotted from published coordinates, the model RAF 48 may have been plotted by some curve fitting analog program. I wanted to add more sq. Ft. to my KR w/o extending the wings so I plotted a 54" cord that is installed tight to the fus, the outer stub [48"] transitions to a 54" at the fus. the coordinate method work for me. I used autocad to plot the profile.

I found by chance, over the Internet, a 'ribs generator' program, designed for radio-controlled models, wih more than a thousand profiles available. You just enter the profile type, the chord of the first rib, the chord of the last rib, and the number of ribs, and voila! You get a PDF file that goes to your printer, with "assembly marks" to help you glue the paper sheets together. I used it to make a RAF 48 profile, with a 48" chord, as per KR2 specs. The trouble is, what I get is different from the KR2 Scale 1 drawing. The KR2 profile is slightly thicker. What the hell is wrong here?
