Gas - Driven Gold Dust Dry Washer.
With this gold dust or nugget dry washer you can set up shop in the middle of nowhere and start prospecting. A decent old gas driven motor and these plans and you're ready to start a project that will yield joy and profit.
Five pages ( 3 sheets - front and back on 2 pages and front only on the other )
B & W photos, illustrations, expanded views, and instructional narrative.
My plans are from original source materials such as books, magazines and other publications and the pages are carefully removed.
