It is not a heatshield. It is a multi-tube EM shield. It simply shields the tubes, usually the 24A ones, in radios like 20, 50, 70 or 90, from affecting each other.
If not shielded, the tubes will interact and the radio possibly squeal.
This said, there are repros available by more that one vendor. I know Chuck Paci made those.
Mark Oppat (Oldradioparts) is another guy. And in one of his old posts he mentioned a 20 shiled might work for 50. Can't say if this is true, but you could ask. He said that because he did not manufacture the one for 50, but did make 20/70/90 ones.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
