Hi Bob
I may have a copy of this book - but if I do it is at my parent's place. I'm hoping to visit them either today or tomorrow so will let you know once I've had a look. It was a great series and I read and re-read them as boy back in the late 60s early 70s. In the meantime there are several reasonably priced copies on eBay.

Kind regards.
