Thanks Hanno; I visit the Archives website regularly.
These are the ones to study:

It says you can send a request for a quotation for a copy of the documents. Some members on ww2talk also offer to scan items in the National Archives; I just don't know the current options given the Covid troubles.
The recommendation for William Hall is available online though

It does describe his actions at Overloon, but sadly there are no details on the name or census number of his tank.
