I found two errors 1 on track 11 and another on track 13
On track 11 sector 8 was missing but instead there was a unique sector numbered 116
On track 13 sector 11 was missing but instead there was a unique sector numbered 116
I put a bit of code in my teledisk lif image converter code to translate the numbers.

I used the disk image provided by Mike and tried to recover the files. As in my first attempt I came across still errors. but this time I was more persistent and was abled during two night sessions to untwist the tangle. My conclusions are that there is still is one single record missing in the image file. I do not know whether this record is in the TD0 file in the wrong place or lost. I was able to reconstruct a best guess of the missing record and the attached ZIP file has the BASIC programs which can be read e.g. into Everett's emulator. There is also a file with my notes explaining some bits and pieces of my forensic analysis.
