Newfoundland covers including censored examples

First flight St Johns to St Anthony.  This trip started on Jan. 29th, 1931.  The plane, a Gypsy Moth, broke down and a mechanic had to be sent by train, then by dog team.  After temporary repairs, the flight continued on Feb. 5th but several stops were required because of mechanical problems and the weather.  All in all, it took almost 3 weeks for the round trip.  There were 7,847 pieces of mail carried on the trip.  The Gypsy Moth was an open air cockpit biplane.  Flying one in Newfoundland in January - February show more bravery than I ever had!  This cover has 2 nice Newfoundland scott C6 (unwatermarked) or C9 (watermarked) airmails on it.  The back of the cover is stamped "Keep Sunday Sacred".

Here are a few more covers from Newfoundland acquired last week at our club auction.
The first is a St. Johns (no apostrophe, which is really a no no - St. Johns is in New Brunswick!) postmarked August 18, 1888 to New York. Back cancelled in Boston on August 28 (forward cancel?) and finally in New York on August 29. The stamp is a #54 issued 1887 A damp q-tip may take care of those hinges eventually.

Also three later covers from 1938, 1940 and 1943 respectively.

A cover with a poignant history  -  the RMS 'NOVA SCOTIA', built 1926 by Vickers/Furness Withy, was a regular on the mail runs from the eastern N.A. seaboard and the U.K. until requisitioned as a troop ship early in WW II.    The vessel was torpedoed and sunk in conflict in late 1942 with the loss of 858 out of a total of 1052 passengers and crew.        One of it's earlier passengers who later became very famous was the author Roald Dahl who as a 17 year old took part in some sort of youth exchange programme with others of a similar age in Newfoundland around 1934.            At this time Newfoundland was an independent Dominion of the U.K. but the guy on the stamp here isn't George V as I'd first assumed  -  might it be a young George who went on to become George VI, possibly ??  anyone know. 
Love the colour of the stamp  -  almost raspberry  -   thanks for looking. 

hdm1950 - thanks very much for that - part of the reason for my ignorance is that the cancellation covers rather a lot of the guy's face - and yes, of course, Ed. VIII was in line for Monarch before his brother George VI, though there was no way the British Government of the day was going to have an American divorcee on the British throne and his obstinacy ultimately got him the elbow.
thanks Peter, well spotted - love the humor - we need it sometimes

I've been trying to find all of the 1919 Caribou issue on cover; but a tough challenge.  Here's a 15 cent cover.  I would really like to find a 12 cent on cover; probably wishful thinking.
