Lot of 8 Vintage Belt Buckles

Lot of 8 vintage buckles that belonged to my father. 2 are Pierre Cardin. 1 buckle says Made in Spain, another says Brass. The square silver has a stamp with a W in an oval. I am not sure of the significance of this. I have shown the back and front of the buckles. Photo shows the measurements. Photos show scuffs on the hardware.
