Publish the paper Walt, the authors are all gone (I think, but you
know better than I) the IRE is gone too; what are they going to do,
come back from the grave and sue you?

The authors didn't own the copyright. (If they did, it would be the
property of their heirs if still valid.) But the IRE isn't gone -- it
merged with the IEE, back in the '60s as I recall, to become the IEEE.
If the copyright is valid, they're its owner. And they might sue.
