I found these at a treasure trove of greatness in Portland OR called the Dollar Scholar. I have 20 or so volumes, each jam packed with well written well documented howtos and diyisms. !974 and DIY was a strong force. This jared my memory a bit as I realized back in those times I made a dasheki from instructions I got from mailing in a card to Zoom. I wish there were pics of that…on second thought…
