Guess strap heels with gold buckle and zipper

Guess black and brown strap high heels with gold buckle strap around the ankle and back zipper. Very old style but worn only few times. Couple of signs of wear. Straps are covered with fabric. Right shoe has a small tear on one of the straps and stamina on another (as shown on pictures). However, the flaws are hardly noticable. As the style is old, I can't find them online and I am not sure about the model. Size 7.5. Heel 4" high.
