The internal label is faded, so the model information was identified to the best of my ability. Size approx. 50-21-135 based on manual measurement. Frame Made in Austria. This listing is for the frames only, as the current lenses are prescription and should be replaced by the buyer. The frames are pre-owned and show some wear, which may include light scratches, scuffs, or minor hinge looseness. Frames have been gently cleaned but further cleaning may be desired before use.
