7 year cycle in 56 year cycle

Hello Hotcoppers - some time ago someone posted a PDF in here called the Washington Defense Fund or Wilson Defense Fund?? It was an article or excerpts based on historical 56 year cycles with 7 yearly cycles inside of that. It showed overlayed graphs from DJI at very early stages - through until 2020 or so. Very clear graphs and easy to read time lines.

I have searched everywhere on the net and cant find it. Does anyone remember it or have it or have the link and would they be kind enough to share?

It was posted a long time ago - before market hit this stage of bottom and maybe before Techs crashed.

Thanks in advance
