Yes, the previous discussion is of interest in connection with Barbara's weight.
But note that not just the French and Belgians have used red, white, blue twist canes. And the canes in Barbara's are flattened, with the colours layed out in strips, and then twisted whereas the other one has solid cylindrical sections with the colours applied around the rod. Not that this proves or disproves anything, but details like that can sometimes lead in a particular direction.
