Both Centrowitz Se and Salazar ran within 10s of the then world 5000 record, 13:06.
Schul and Dellinger in 1964 all marks at big meets on US soil I believe.
Going back a bit further, 2-3 others at least capable. Gold medalist in 2500m steeple 1904 and near world record miler George Orton clearly capable and Zamperini close.
Of the 4 runners you listed none of them had a win in Europe. Does not follow instructions.
