Very odd . . . I don't recognize the cover or the story about the tester, but other parts, I do! Could some of the articles been recycled?

The first issue I got was the one with the Omega on the cover.

The rear ejection Sprint article looked very familiar to me. It is also in the Jan '71 issue

MRN Jan 71

and I would have had to see it sometime at least a few years later :)

Thanks for posting that one OH. I built one of those mid-eject Sprints but I hadn't seen the NARAM special MRN that the op posted.
