Trying To Identify The Year This Tv Was Made

[VA561]

I have an Rca color tv and I am trying to find a picture and info on the year the tv was made. Someone on Vk posted a 1967 Rca color catalog. My tv cabinet looks exactly like the "Chatillon " model execpt for the model number and the control panel. The '67 catalog calls this model GH-768. My set says GH-759 on the back panel. I think maybe a '66? Any help is appreciated.
