M-41 magazine modified to fit 208s/215s pistol

I've been looking for Ed Hall's article on modifying S&W M-41 magazines to work in Hammerli 208/215 pistols. I've searched everywhere I can think of and keep coming up with nothing. Does anyone have information on this modification ? Thank you.

Thank you Shenneba, that's what I needed. I have a time when I search
for stuff, probably wrong wording. Anyway that's what I was looking for.
