Bryan,
I do not have HV cage doors for either one. it appears that both of these chassis had flyback troubles, and I am assuming that the shops that originally looked at them tossed them to the side or reused them on other sets.
However, I do recall another 15 in that old tv shop. Next time I go I will take a look for you. IMS, most of the color sets I saw in that place had flybacks that went south, so that set may have a missing door as well... but I'll look for ya.
