this was what my sponsor wrote for me (well i wrote it actually, he signed it) - ticked all the boxes
Dear Sirs
Following my previous letter, releasing Mr ??????? from my supervision, I write regarding his request to be granted an “open” certificate.
I can confirm that Mr ?????? has demonstrated competence in all aspects of rifle shooting both whilst under my supervision and since being released, and is fully capable of determining if land is safe and suitable for use of firearms.
On this basis, I fully support his request for the restrictive condition being removed from his certificate, and the certificate being made “open”.
Should you wish to discuss this matter, please do not hesitate to contact me
Yours Faithfully
GOD
