This ZZR is an inch-perfect copy of a Huret Svelto - with some characteristic Eastern European touches - nuts that are slightly too large, a mixture of chromed and zinc-plated finishes and a slight, but distinct, heart-warmingly agricultural feel.

I believe that this example is an earlier version with smoother stampings and steel pulley wheels with ball bearing races.
