Possibly other people that may have archived training material is Cosford, but don’t hold your breath, I sadly skipped all of my course notes at the end of all my RAF training courses, there was so much of the stuff and I just didn’t have room to store / move it all around the country, I have some of my mechs course stuff from Saints up at Carlisle. My VC 10 course notes were used on LSS and whoever last completed the courses replaced the previous users notes in the filing cabinet, to be dragged out when we had the weird and wonderful problems the manuals never covered in detail.
