One Fried Zenith Porthole

[VA561]

I carefully removed the 16" picture tube in my 1950 zenith porthole tv. I took the chassis out becuse I was going to do a complete recap. When I turned the chassis over, I couldn't believe my eyes. As you can see in the pictures, what I believe is the high voltage transformer section melted. It looks as though that section has been burned for quite along time.

Is it possible to replace that part of the chassis only and salvage what looks otherwise to be a perfectly good chassis? How hard will it be to find this part?
Any advice would be greatly appreciated, especially in regards to where I can locate a replacement for the fried section.
