Developed in 1936 as a mailplane for Deutsche Lufthansa, the Heinkel He 116 made use of design features of the He 70 and He 111, particularly the elliptical wing and tail surfaces. The aircraft was to have been powered originally by four 373kW Hirth engines, but these were not available in time and the 179kW Hirth HM 508 engine was substituted. Eight civil aircraft were built with the designation He 116A-0, the first making its maiden flight in the
summer of 1937. Two of them were purchased by Manchurian Air Transport and made their 15,337km delivery flights from Berlin to Tokyo between 23 and 29 April 1938, in a time of 54 hours 17 minutes. Another was modified for record-breaking, with 179kW Hirth HM 508H engines, a wing of increased span and area and provision for rocket-assisted take-off equipment. Designated He 116R, it set a distance record of 10,000km in 48 hours 18 minutes, beginning on 30 June
1938. An He 116B long-range reconnaissance version was also developed, the last two civil aircraft serving as prototypes, and a total of six was built.

Here we see the original eliptical wing used by both the 116 and 111. The 111 later switched to a swept-back wing with a straight trailing edge.

I have an ARCO Publishing Company book called "HEINKEL an aircraft album," by P.St. John Turner dated 1970 that has a photo of the type. It has a stepped nose, not the glazed, smooth-contour nose shown above. That matches a drawing I saw in WW II era magazine my father had that showed the stepped nose characteristic. The magazine, which was dog-eared by the time I saw it in the 1960s, has disappeared. It was avery mysterious airplane. I remember the magazine made a big deal of how smallthe aircraft was despite its 4 engines. The book doesn't provide any special or different info from the profile above, unless there is a significant difference between 10,000 km and 6,214 miles
