Sears Color TV 15gp22 clone

Just wondering if anyone still remembers this model... Much discussion has been noted here about the ct-100 and 15gp22. Well here is a little talked about TV model from the mid 1960's. Early in the 1960's when the japanese were just starting build television sets many were licensed copies from American manufactures. Well the first Color TV set built by matshuista (Panasonic) was a "updated" CT-100 sold under the Sears label. The CRT has the japanese designation (ie the 15 was just to metric) and much of the tubes updated to later types. I saw one of these sets in 1970 for service. I measured the CRT compared diagrams to the CT-100 and it had the same electro-static convergence...wow! Anybody (maybe an old Sears tech) remember the model ?
