I got my med records last month. Took about 2 months - no charge.
The records were batched. There were some omissions where i had been sick away from base.
My first audiometry test was in 1981. I was immediately downgraded. Every subsequent test at my.annual medical was recorded though there were variations in some years. I must get round to checking year on year.
Before 1981 tests were down with the 'standard med assistant whisper down a dark corridor.
