Waterman Expert Users needed

Specifically, anyone with both the FP and RB. I have a couple of Rollerballs that I haven't used in a long time. Since you can buy replacement sections from Waterman, I'm wondering if the FP section will screw onto the RB barrel.

If it does, you may still need a FP cap as there probably won't be an inner cap to seal the nib. I know with Pelikans that is how it's done -- the roller ball cap is different.
