John, good to see that you got Murray's OK to put this story up here. Even if you had hopes for more!

Folks, Murray did self-publish a collection of some of his yarns [including this one] in 1988.

It's titled 'Brother to the Dingo'; ISBN 0731626095

Copies do come up on the online book search engines occasionally, but they're getting rarer and pricier.

Your best chance is to plug that ISBN in at www.bookfinder.com from time to time - none available at present.
