6 X 9 Kodaks
I've a Tourist, a Monitor and a Special 120/620 Kodaks with "Special" (in red) lenses and good shutters. All perform admirably after a good shutter cleaning and finding the "sweet spot" by mounting them on a Baby Graphic for tests.

I have also put NOS bellows on several Edwardian 120 Kodak folders with "interesting" results.
My Agfa and Zeiss rangefinder 120 cameras work fine. The Kodak "Special" lenses are perhaps better than one may find on the German cameras and the shutters are as good. I nearly always get good results from the Kodaks with the guesstimate method of focusing. Infinity and hyperfocal distance never change. Use a tripod.
