The missing back question puzzled me for many years, until I started asking around, a lot of the older people that I talk to, stated that they knew someone who worked on TVs or radios or electrical stuff, and they always took their stuff there because the repair shops cost too much money. Back in the day there were literally tens of thousands of men and women trained by the US government for electronic assembly and repair due to World War 2. So there you have it missing back or simply not put on by amateur repair people who saw them more as a pain in the butt than anything else. So much different than today when you simply just throw it away if it quits, because no one knows how to repair anything and nothing is made to be repaired... Even trying to buy modules to swap out in the flat panels is cost prohibitive. I would think someone could make a pretty good money in the niche market for making reproduction TV and radio backs.
