JUST ADDED TO THE ARCHIVES:
The Strat and Les Paul were only several years old when Mechanix Illustrated magazine published these plans, penned by Captain America creator and artist, C. C. Beck in their September 1959 issue.
Like many how-to articles from this era, the article is somewhat vague in carving and building techniques and instead puts most of its weight into the diagrams with measurements.
We’ve taken the actual page scans (advertisements included!) and put them together in one downloadable PDF file. If you’re daring enough to build this, let us know.
