One Hermann Hesse Typewriter Leads to Another

I'm absolutely hopeless at translating German to English, so whether or not the last paragraph of Ernst Martin's eight-page entry on Karl Drais (see previous post) refers to Hermann Hesse I cannot be sure. Maybe it's just my imagination running away with me (I'd like to think it does - mention Hesse, that is). 
What I do know is that planting the name Hermann Hesse in my mind yesterday led directly to me finding today this wonderful image of Nobel Prize laureate Hesse (1877-1962) at his Remington Quite-Riter portable typewriter. The photograph was taken by his Hesse's son Martin (1911-68) in 1960:

Here is a slightly younger Hesse at the same Rem, but photographed from a different angle:

The first find, in turn, led me to this much earlier image of Hesse, at his Smith Premier No 4:

This led me, in turn, to the ever-reliable Georg Sommeregger, who knows a thing or two about Basel and, as it turns out, also about Hesse's typewriter (see). 
To my considerable relief, clever Georg was able to tell me this: "The typewriter was bought in early 1908 at the company Klingler, with the famous italics ... On this machine Hesse wrote tens of thousands of letters, as well as nearly all his manuscripts ..."
Relief, because another of my discoveries today was this letter, typewritten in a cursive type by Hesse to German businessman, social reformer and anthroposophist Emil Molt from Bern in November 1918:

If this sketch of Hesse at his Smith Premier (which he apparently continued to use until 1942) is by Heinrich Böhmer, it would have to have been drawn before 1930, the year Böhmer died, aged 78. The postcard is postmarked Zurich, October 17, 1939.

For reasons I cannot explain, Hermann Hesse led me in turn to another Hermann, Hermann Langbein, and a portable typewriter I cannot identify:

Hermann Langbein (1912-1995 ) was an Austrian communist resistance fighter. The former concentration camp inmate in 1954 co-founded the International Auschwitz Committee. He joined the Communist Party in 1933, escaped after the Anschluss of Austria from the so-called "Greater German Reich" and then fought in the Spanish Civil War in the International Brigades against the establishment of a dictatorship under Franco. He fled to France in 1939 but after the occupation was shipped to Germany in 1941 and taken to the Dachau concentration camp. He was transferred to the concentration camp Auschwitz I (main camp) in August 1942. In August 1944, Langbein was transferred to the Neuengamme concentration camp. On the evacuation transport to Fallersleben east of Hanover in mid-April 1945, he jumped from the train and fled by bicycle to Austria, where he arrived in his hometown of Vienna in May. From 1955 to the early 1960s, Langbein was secretary of the Austrian Camp Community Auschwitz and fought for compensation for former concentration camp prisoners. He was ejected by the Communist Party in 1958 after criticising Stalinism in the wake of the Budapest uprising of 1956.
