| This is the first generation of plastic carrying case that Curtis put out. I'd guess it's from the late 70's, or early 80's. Very limited supply. These have a separate compartment for the carriages, with a plastic cover on it. Most of the time, the clip that holds this compartment shut is missing or broken. The hinge on this unit is made of plastic, and being 30 years old usually is cracked. We will send you one out that is good, but some minor defects may be present.
