I've had a Rollei XF 35 for a while now and I thought I would take it out for a spin.
It seems a common problem with these that the rangefinder gets out of verticle alignment. Luckily it pretty easy for a tinkerer like me to fix.
I loaded it up with Ektar 100. I was pleasantly surprised by the results. The images are sharp, contrasty, and the lens seems well resistant to flare. I have attached a pic of the camera and some examples.
