Typewriters are shown in many films, being the 'every-day' objects that they were. Most are fairly standard and recognisable machines. In the '37 film 'Rhytm in the Clouds', it looks that a less common machine is shown.
The film itself is a low-budget, fairly simple comedy with music and some romance. Typical of its genre/time; unpretentious, light entertainment. (If curious, the film can be found on the net - a.o. on the Archive.)
Around 8 minutes into the story, the songwriter (Warren Hull) is sitting at his typewriter in his swanky apartment. It looks quite clearly a Remington portable #5.
When the story again is at his apartment around the 40 minute mark, the machine is shown more clearly and it definitely is a Remington streamlined #5 portable typewriter. (Swanky, spacious apartment - with a white phone too.)
What is notable and unusual is that the machine shows quite light in the film. The regular black #5 typewriter would show very dark in the picture, but this machine definitely is not black.
Remington made #2 and especially the #3 portables in many colors, but the #5 came in black. Only by the late 'forties was the #5 made in crinkle grey, but this scene was filmed in '37. Did it also come in colors? It did come as a Smith Premier machine with a red top-cover. The machine shown is however not red, as reds would have shown darker with the film used at the time - as well as the whole machine being light.
A brief search on the hive-mind that is the internet turned up the Remington teaching typewriter:
This is a streamlined #5, but finished in a greyish shade of tan. That would be about right for the light shade in the film. (For larger images; there is currently one on offer at Etsy.)
Did the prop department of Republic give the songwriter a beginners, teaching machine? In the last scene with the machine, the camera briefly shows the keyboard - no visible signs of colored columns of keys. Maybe they went to the trouble of painting a machine to match the general luxury of his apartment - for a low-budget Republic production, that however seems a bit too much.
So maybe the wealthy songwriter did get a colored keys teaching machine :-)
