There was a roll of partially exposed Kodak Verichrome Pan film in this camera. I developed it and here is the best out of three images:
That's precious! Great find! I have the feeling the camera was set on a table or chair for that. If it's on a steady object in portrait mode, and you use one hand to gently press down on the body to give it some weight for when you trigger the shutter, it shouldn't get shake.
To me that sounds impossible.
I did my best to brace against the railing, it was not enough. But the scene was of a beautiful remote Greek village at sunset, so I had to try.
