1951 Registered / Special Delivery / Air Mail w/ Unitrade E11 10c SD stamp, 270 20c Peace, 286 3c George VI & 301 10c Fur to U.S.A.
Moncton, N.B. Sub. No. 2 to Akron, Ohio
20c registration + 10c special delivery + 7c air mail 1st ounce + 5c 2nd ounce means this may have been overpaid by a penny. Total 43c
Also note that the 10c SD stamp is uncancelled so this adds to the puzzle. Was this a misunderstanding of the regulations? I believe if the sending PO affixed a US special delivery stamp (which was allowed) they were not supposed to cancel it, but in this case it is a Canadian stamp. Or did someone stick the SD stamp and sticker on after the fact? Still would be overpaid by a penny. Let me know your thoughts.
