Write to your examiner explaining the situation. Enclose a SAE, copy of the FCL172 and your 'type validity rating' page. I am sure he/she will understand and will sign and send it by return.
Be aware that you cannot fly PIC without the type validity rating page alongside your license, so while it is away, you are hobbled.
That is what my examiner did, at any rate. Splendid chap!
