On the left, your basic Japanese KayKraft copy (see Granada et al.); in the center, a Model 526, very similar to a Cameo. No headstock logos, but apparently there are internal labels. In addition to these specimens, there was also the Model 516, an electrified A-model produced between 1977 and the early 1980s. The instrument at right may be one of those, or it may be of more recent vintage.
