Thanks Tim. It's very unclear which cabinet this TV chassis was intended for, I guess all 3 models used the same chassis?
Anyways I have now created a page on my vintage video site on this TV set
http://www.troysvintagevideo.741.com/andrea.html featuring all the pics I've posted here along with info and description.
Lastly I forgot to mention, this television chassis has channel 1 which I was told only been used in the early post war sets before channel 1 was taken out of service.
