Heinkel He 70, used as both a fast passenger/ mail carrier, and as a light bomber/ recon aircraft in the 30s. With limited use as a bomber, it was deployed as a recon aircraft in the Spanish Civil War/WW2. Good to see are the elliptical wings and tailplane, as in the later He 111 https://twitter.com/jerijerod14/status/1354337511670222849
Recognizable features are the wings/ tail plane, & the rounded stabilizer horizontal. The bulge on top houses the cockpit and adds room for the passengers (4-5) The nose section is distinct too, with the prop hub sticking out aggressively on the lower part of the from the cowling
The aircraft was powered by a BMW VI, a 12 cylinder water-cooled engine. It cranked out +700 jeremy clarksons for take off, not bad for the time. This and the planes design gave the aircraft a competitive top speed but it was soon overtaken with the rapid progress of the 1930s.
The plane was also exported to various countries, including the UK. There it was powered by the Rolls Royce Kestrel V, which gave it bit more whooomp. Hungarian He 70s also changed the engine to the Gnome-Rhone Mistral, a highly successful twin row radial (picture: Fortepan)
Other cool features of the plane were a retractable landing gear, which was like the definition of luxury back in the day. The cabin wasn't too bad either, if you wanted to get from A to B fast and had the money, the He-70 could get you there in record time and in comfort.
Talking about records, Heinkel really liked showing those off (and why shouldn't he). Here is a list of records flown with the Heinkel He 70, compiled by the company.
The military version had some changes. Bombs were added (like 4-6 50kg bombs as maximum), and a single 7.92mm MG-15 machine guns for defensive fire.

Hey! It was the 1930s, ok, that was not that bad for the time for the He 70 size.
Other changes are easy to see. The civilian version (L) had two doors, one for the pilot, one for passengers. The military version (R) has one. Good to see are the defensive gun & aerial mast/ navigational equipment on top. Some persons ...backside... gives you a sense of scale.
The He 70 was the first 'modern' success story of the Heinkel company, albeit that it already had ~1000 employees by the time it came out. In a slide by the company, you can see its similarity with the later He 111, which is perhaps the most famous Heinkel aircraft of all time.
