The binoculars and the hot dogs
There are two curious things about the scene in downtown Winnipeg, where the Nazis sell off their bincoluars to raise money for food.
We learn that Lohrmann sold the group's binoculars at a pawn shop for $7 (Canadian). First, even in 1941, $7 for a pair of what must be first-class binoculars is pretty cheap, even taking into account that a pawn shop doesn't pay retail prices. Binoculars are not cheap, and the type they must have had would certainly be costlier than the usual. I think the Germans were ripped off for a mere seven bucks (about $11 US at that time).
Second, the binoculars would certainly have carried some identifying marks -- where they were manufactured (surely) and, very probably, whose property they were: in this case, the German Kriegsmarine. Wouldn't the pawnbroker have been suspicious? Surely he'd have looked them over to determine their provenance and worth. Point being, a good (or honest) broker should have seen something on the binoculars that would have identified them as foreign in origin -- almost certainly German -- which in turn should have alerted him to the possibility, at least, that these glasses were being sold by one of the crew of the by-then famous U 37.
A more amusing side to this comes in the scene where the three men are eating their hot dogs (dare I say frankfurters?) they bought with some of the cash they got for the binoculars. Notice how Hirth (Eric Portman) eats his: instead of starting at an end and eating his way along the bun and dog, he turns the dog sideways and eats it lengthwise, munching on the bun but little on the wiener itself. Since no one eats a hot dog in this manner, I don't know whether this was deliberate, or a reflection of Portman's own unfamiliarity with the hot dog, then virtually unknown in Britain but already a Canadian treat from across the 49th parallel.
This reminds me of the picnic President Roosevelt held for the visiting King and Queen of Great Britain in the summer of 1939 on the hillside of his Hudson River estate, Hyde Park. Ever the natural aristocrat, and with the American love of puncturing stuffy traditions and democratizing situations, FDR served George and Elizabeth hot dogs, with which they were thoroughly unfamiliar. When the Queen asked Eleanor Roosevelt how "one" ate them, Mrs. R. replied, "You just start at one end and shove." Evidently the two, particularly the King, enjoyed the experience. (This was the occasion on which Roosevelt stayed up late with the King, discussing the world situation, until 2 in the morning, when he patted the royal on the knee and told him, "Young man, it's time you went to bed," all of which caused the King to remark, "I wish my own ministers would speak to me this way.") Anyway, obviously by 1941 hot dog etiquette had not yet penetrated to the UK, and poor Eric Portman had to wing it.
Speaking of which, I wonder how he'd have done with Buffalo wings?
