Thank you for all the replies. I have been away for the weekend, so i haven't had the chance to check in and reply!
Thank you Dan. I'll definitely go for better test shots. During the week, I don't have much time to do test shots in good light. I'll have to see what I can do over one weekend. It may be that the curvature is better. The mountain slope, which is sharp in the centre, is a good 100 meters away from the camera. The wall can't be more than 25 or 30 meters away. Even that skew light pole is sharper at its base than at the top. Will try and find a flatter target.

Interesting. Thanks. It has always been my habit to advance the transport prior to taking my image. Seems like a good habit

The film advance doesn't stop at the frame numbers when a film is in the camera.
Interesting. Hopefully I can have it looked at by a qualified repair man. Perhaps I could simply buy a new Rollei. A 2.8E or something reasonably priced.
