By the way, this timing "magic" was achieved with 1940s electronics.
Shouldn't be any problem today.


It was done with a high speed switching component that is still
restricted.

Yes, but krytrons are also a 1940s technology, and far easier to
duplicate than say an ultracentrifuge. And I bet one can buy them from
non-US sources.

With high speed solid state electronics commonly available who needs
ancient tube technology?
