Here's a couple of links to our NZ auction site where there is some SMLE magazines currently listed. I don't think bidders are allowed from outside NZ. I used to have some myself but sold them off. Could purchase on your behalf and send to you if there was not too much hassle with regulations around gun parts. None at this end anyway but maybe at yours?
