Evening Ian, AFQR, BJQR and UKQR are books by Air Britain is a good way of Identifying jet airliners, it has all the registrations and aircraft types from all over the World, they cost £8:95 apiece and are published annually. AF stands for Airline Fleets, BJ stands for Business Jets and UK stands for light aircraft in the UK, QR stands for quick reference. Hope this helps, Chris.
