Michael, I think you can still buy them from the club. click on the “Regalia” heading at the top of the web page then on the first heading which includes a reference to Hints and Tips.
Are you sure you want them? I got hold of the two booklets expecting to see words of wisdom and most of it was how to bodge it up. I put them in the bin to ensure the innocent and unwary didn’t get led astray. Same treatment for the Haynes manual. Far better to get the proper MZ manual.
