WWII Airmail from India to the Goblin Ha'

I know nothing at all about this item other than it's been posted from India to the
Rev W. Serle, Duddingston, Edinburgh, and has been forwarded to the Goblin Ha'.

Note the purple frank saying that it has been "Passed by the Censor".

Not sure if the "On Active Service" applies to the sender or the recipient.
I presume the latter.
