Good news - I found it ... had an ebay alert setup and at last the original cassette tape appeared ... awaiting delivery

Thanks all for the help. I will see if I can track down the 1994 version and let you know!

I know there's a few different audio versions of this knocking around but I'm specifically searching for this one http://www.enidblytonsociety.co.uk/book-details.php?id=2674&title=Five+Go+To+Smugglers+Top+%28BOW+102%29 Its the Rainbow 1983 dramatised audio version. Many happy times listening to ...
