Is This A Hong Kong Censor Marking? (China To Canada)

This is a WW2 air mail cover from China to Canada that was opened for censorship in Canada and resealed with a transparent censor label. There is a Victoria, Hong Kong transit mark on the back dated 04/11/1941. I cannot read the dates in the Chinese cancellations.

I am interested in the purple boxed "Not Opened by Censor" cachet that is partly covered by the Canadian label. I am assuming that it was applied in Hong Kong but I do not have any reference books for that area and have not found anything on the web.

Any info about this cachet would be most welcome.

Same mark on a cover from Hong-Kong to the States


And on a cover from the Philippines to Hong-Kong


(not mine)

The examples showed are not the same marks what John posted.

Both the censor stamps above are very common Morenweiser type 7C marks which are characterized by the break in the upper frameline between T and O whereas John's is way scarcer Morenweiser type 7F mark which is characterized by the longer left vertical stroke of N of CENSOR than the right one.

The oblong NOT OPENED BY CENSOR violet rubber stamp is Morenweiser type 7F censor mark of HK Censor Station which functioned from Sep 1,1939 to Dec 24,1941.

Ha ha. The word same is now edited out.

Ha ha.It's back,and here to stay !

Good. It will remain as an exemplification of your ignorance.

Thank you for the replies and confirming that this cachet is from Hong Kong
