“All manner of treasure was unceremoniously dumped in the “spirit of Vatican 2”.”

This monstrance probably was “dumped” many decades ago - long before Vatican II. Otherwise someone in the area would still be around who recognizes it. No one does.

veetu was 50 years ago, well within the time frame you cite.

The cathedral in my diocese chopped up the high altar and put it out as rubbish after the council.

In another diocese it was chopped and used as parking separators.

Pure conjecture on your part. The monstrance was found over two decades ago.

Does the article say this? I don't see it.

Also, wasn't this monstrance just recently been made known to the public? If so, isn't it possible that someone who could recognize it just hasn't seen it yet?
