I can't keep up with all the names, but you'll get the drift.
3.26 JB Phones police station. Officer A answers, notes time on pad, takes details - JB, son, informing father phoned him saying daughter has gone berserk with gun. Officer A puts JB on hold.
Am I mistaken - does officer a despatch car?
Officer A phones Officer B in control room, saying father reports daughter gone berserk with gun.
Officer B records details and time xx
Officer A takes JB off hold - JB complains he's been on hold 11 minutes (Anne Easton mentions JB complaining about the delay).
Could Officer B have written the time it was when he ended the call with Officer A and took action, despatching a car. Is that why it was 3.36am.
Officer A recorded time at start of their call.
Officer B recorded time at end of their call.
?
Other way round I think. Officer A could have recorded the time he ended the call with Jeremy, and Officer B recorded the time that Officer A called him. 
Just to put some names to it:
Officer A who took the call from Jeremy is PC West, AKA 1990. He recorded the time as 3.36.
Officer B is Malcolm Bonnet in the information room, who was actually a civilian rather than a police officer. He recorded the call from PC West as being at 3.26.
-----------------------------------------
But Sheila was not Jeremy's daughter, and the guns at the house belonged to Ralph...
It doesn't matter. You have to remember that Jeremy quoted to PC West what his father said, then PC West had to try and jot it down and then repeat it to Malcolm Bonnet. I can see how all that happened.
-------------------------------------------
So, how did Malcolm Bonnet end up with the log from the scene, written in PC Wests handwriting, with the details of Ralph's call on the reverse side?
The log from the scene was not in PC West's handwriting in my opinion. I think Malcolm Bonnet wrote the log of the events. He said he kept the log until he went off duty at 5.45. The log of the events from the scene looks like his handwriting to me.
... But, details of Ralphs call, timed at 3.26 am, was a photocopy on the reverse of an orignal log, relating to the scene, how could a copy of the phone call timed at 3.26 am, end up on the reverse of an orinal log from the scene? It should be clear to everyone, that somebody has copied the details relating to the 3.26 am, call, onto the reverse of the other log, and that whoever did this, did not want anyone, to get their hands on the original, or to see what was recorded, on the reverse of the original phone log.,
