What nickname did the Ju 52/1m CF-ARM receive in Canada?

Before the famous trimotor there was the Ju 52/1m, the single-engine version, of which very few examples were built. In late 1931, James A. Richardson's company Canadian Airways received the sixth one, with serial number (Werknummer) 4006 and registration CF-ARM.

The aircraft was first re-engined with an Armstrong Siddeley Leopard radial engine and later with a Rolls-Royce Buzzard. In Canada it earned the nickname "Flying Boxcar" for its cargo capacity: it could carry 2,000 kg (4,400 lb) and had a maximum weight of 6,600 kg (14,600 lb). It was used mainly to supply mining operations and other activities in remote areas with equipment too large and heavy for other aircraft of the time.

The Ju 52/1m remained a short production run, while the trimotor Ju 52/3m, designed as a passenger aircraft, was built in far greater numbers and became the Luftwaffe's basic transport. The CF-ARM was not preserved, but its memory was: at the Royal Aviation Museum of Western Canada, in Winnipeg, a replica of the Ju 52/1m is displayed in its colors, made by converting a trimotor into a single-engine aircraft. The same museum also holds the CASA 352L T.2B-148, one of the Ju 52s built in Spain after the war. The Ju 52 had a low cantilever wing with duralumin spars and corrugated skin, and the trimotor was used in the 1930s mainly as a 17-seat commercial airliner; in civilian service it flew with more than a dozen airlines, including Swissair and Deutsche Luft Hansa, as a passenger and cargo aircraft. Some examples of the family are still flying in the 21st century at airshows and on sightseeing flights.
