Postscript.
A licence came back in the post today. Impressive packaging, it was inside an envelope, inside a jiffy bag, inside a courier bag !
My EASA licence has been re-issued and my instructor privileges are shown as "CRI For/SEP(land)/FCL945".
My UK licence, which has my CRI on it, hasn't been re-issued.
There's no explanatory card.
There was a receipt for £59 !
Fortunately, I instruct at a school with a friendly examiner, I'll go and get him to explain the paperwork to me.
