Thank you so much for the advice. I am off today in a few hours to use the camera again with the advice above in mind.
Just to make sure I understand;
1. Focus overall.
2. If perspective needs corrected use read tilt or swing.
3. If needed then front tilt or swing.
4. Focus and refocus front standard via rail.
5. Stop down and close lens then cock shutter.
6. Insert film holder, remove slide and take picture.
Thank you and fingers are crossed!
