Opened and Examined by Five Censors

Ken Lawrence has provided an example of a cover that was opened by censors in 5 countries. This may be a record. Can anyone match or beat it?
His description of the cover:
The registered airmail cover illustrated here, addressed to an Italian artillery officer interned in Switzerland, was mailed at Sao Paulo, Brazil, in late December 1943. After being examined and passed by the Brazilian censor, it flew north aboard a Pan American Airways flight from Natal that transited Miami on December 30 and arrived at New York City the same day. There it was examined by the U.S. Office of Censorship and released back to the mails on January 5, 1944.
The next stop was Bermuda, where British Imperial Censorship had its look and held it more than a week before sending it onward to Lisbon where it arrived on February 12. From Lisbon it went to Paris for examination by a German censor and another delay; next it was on to Bern on March 15 for the final censorship inspection. By this time the internee had been relocated from a camp at Munshenbuchsee to one at Mürren (not reachable by road) where it was delivered.
