I have a 1914 Kodak 6x9 (with Cooke triplett lens,) and a 1937 Voigtlander Bessa. I mostly shoot HP5 because I want the speed as I use filters a lot. I love uncoated lenses! Both of these cameras have waist level finders, and when you use the camera that way the camera is very steady. Few people using non-pro cameras in the 40s and 50s were shooting color film as it was very expensive. When I use it, I tend to shoot either Portra 160 or 400. I also agree that Pan F is a great film for these cameras if you don't mind the slow speed.
