Hi Keith, Just got back from my hols so have missed your post.
The piece you have is Merlin quite a common pattern but very nice none the less.
92 is prob the year date but Richard has produced these over the years since he started in 1979.
If you would like to no more of Okra and Richard go to my web site where you will find an extensive Biog and also many many of his works of art.
Now back to dreaming of the hot sands and Pina Coladas.
Regards Mike
