Many thanks chaps for your replies.
After a bit more searching on this excellent forum I came across an image of the said plate in perspective, I didn't realise how small it is.
I did eventually find a supplier in France who is asking 60€, which I find extortionate for such a tidily bit of ally.
Your suggestions got me thinking.
I designed my own using MS Publisher, then uploaded a transparent PNG file to Vista Print. It will be printed on a 15cm x 15cm piece of 3mm aluminium sandwich plate, I will then stamp in my chassis number as did Morgan back 79. The type face is not Identical but close enough to satisfy my local Control Technique (French MOT) guy.
The best bit is that I had enough space to print a spare chassis plate should I mess up the stamping, several Morgan logos, the 'CAUTION' plate etc, all for 40€ shipped.
If any one would like a copy of the file I am happy to share, FOC of course.
