Englishal,
You have tried to open up a can of worms.
The CAA are being kind to you by ignoring the statement in your letter regarding the failure to complete the requirements for revalidation.
If they were the suspicious types they may ask questions like;
Has this person forged the revalidation?
Has this guy and the examminer revalidated the rating outside the required time period and tried to cover it up by loosing the form?
Why has this guy not had the sense to get the form and include it with this letter?
Who is the examminer and what are we going to do with them?
Regards,
DFC
