the RNZAF inherited from the RAF
When I left the RNZAF I was presented with a nicely bound passport sized "Record of Service" beautifully typed with some very nice comments from my former boss.
I did have occasion to have to write to the RAF once for my record of service. It turned up as a photocopy of a dot matrix printout on old dot matrix printout paper. Service recorded as "Satisfactory"...
