Robert, in a nutshell, Cortez guitars were made in Japan and exported by a company started by a man named Jack Westheimer. Mr. Westheimer is credited with being one of the first people involved with global guitar manufacturing/importing. Along with Cortez, his name is associated with Kingston, Teisco (later known as Teisco Del Rey), Silvertone, and Emperador brand guitars. Incidentally, the Everly Brothers thought highly of, and played Emperador guitars before the J-200 and Everly "signature" Gibson guitars. Cortez guitars later became Cort guitars. Cort guitars are manufactured in South Korea and Indonesia. In recent years Cort guitars are credited with making economy priced guitars for many big name companies such as Fender and Gibson and turn out an estimated 1,000,000 guitars annually. Because of this volume of production, Cort can manufacture high quality guitars under it's own name, for a fraction of the cost of the more sought after brands. Cort also manufactures it's own line of "signature" electric guitars such as the "Hiram Bullock", the "Neil Zaza", and the "Pagelli". At one time, they manufactured a great signature jazz guitar, the 7-string "Joe Beck" model. This guitar can be heard on the Jimmy Bruno-Joe Beck album "Polarity".
Robert, if Cortez guitars are anything like Cort, they're probably well made and under priced. I currently own a used, Cort MR710F which I bought for $150. It listed for about $450 new and is comparable in construction and sound, to guitars costing 3 or 4 times as much. Like your Cortez, it has flamed-maple sides and back, maple neck and a solid spruce top. Here's a link to the Cort MR710F:
