Need the back cover and the left side front control door. Any help will be greatly appreciated. Thanks!

It might help to put the brand and model number in the title rather than just "this set".

Sorry, my fault. It is an Admiral from 1952, it is a TV and radio combo. I don't know the model number since it doesn't have the back cover.

Parts like that require a lot of time searching and inquiring. There are many collectors out there with hordes of parts set, but often hesitant to search through them. Sometimes you end-up having to buy a parts set to get what you need. I've had to make TV backs from fiber board and perforated steel stock. Good luck.
