That is RK as in reverse Kingussie?

It is the design I settled on some years ago, after trying various options, including the Kingussie, and I have not been tempted to try any other style for my everyday kilts.

I have some fabric that I want to make into something posh and the box pleat or military box pleat have suggested themselves, but - I don't know if they will ever materialise or if it will be the RK all the way.
