Hi

A friend recently picked up this Yaz bat and asked if I could gather some information for him. The bat seems to date to 1977-1979 labeling era. It measures 35 inches and weighs 31.5 ounces (there is a piece missing from the back of the barrel that would probably add an ounce or two). The bat is a K48 model and nothing is stamped on the knob - there is some faded black marker but I can't make out what it was.

After reading some other posts on the forum it seems he did not order this model during this era. Is this a promotional bat? Any help would be appreciated.
