Whatever happened I for one would still like to see some kind of documentation to confirm that the two telephone logs were discussed in court. Scipio got the information from somewhere. So I would like to know where, as I have not heard this before?
West's trial testimony as well as the exhibit files.
West's c1 log and Bonnet's log were both among exhibits that COULD be used at trial if desired. Both sides gets a copy of such documents and sees them. So that means the defense saw both logs.
The exhibit submitted for use as a trial exhibit was Bonnett's. That was the one admitted into court as evidence that the jury was free to look at if desired. The jury can examine any exhibits admitted into evidence.
West's c1 log was used to refresh his memory. You are allowed to allow witnesses to refresh their memory with notes. So his was admitted into evidence in court only through testimony- he read from it. It wasn't admitted formally as a document that the jury could have looked at like the Bonnett log was. The jury had to listen to West's testimony to understand about such log.
Here is where on direct examination where the judge allows West to use the log to refresh his memory and shows him reading from it:

I didn't copy it all they discussed the log contents more but this illustrates my point.
On cross examination he was asked about the time difference and the question specifies 3:26. Where did the defense lawyer get 3:26 from? He got it from Bonnett's log that was admitted into evidence at trial.

So the notion that the trial defense did not know about both logs is ludicrous.
All that happened in many years later someone decided to make up the claim that the trial lawyers did not make up- that Bonnett's log reflected a call from Nevill to Bonnett. Instead of admitting they made up something that the trial lawyers did not consider because it was meritless they created the cover story that the trial lawyers were unaware of Bonnett's log, which is nonsense, and that is why the trial team did not advance the claim. They didn't want the truth to come out which is that it is meritless and that is why the trial lawyers never made the claim.
