Early Dynafit bindings were first known as “Low Tech” and virtually hand made by inventor Fritz Barthel and his helpers in the basement workshop of their multi-generation family home in Austria. This is somewhat the second production model (see first production model). Note the smaller boot pins on the toe unit (right in photo below), this size would go on to become the standard for Dynafit. Most other details of the binding remained the same as those of the first production model.
One fascinating aspect of this binding is how the heel torsional (sideways) release spring and cap were based on that of the Iser binding, as shown in our display of the first generation tech (now known as Dynafit) model ski touring binding.
