George Gush’s Wargames Rules for Fifteenth to Seventeenth Centuries (1420)-1700) were developed from the early WRG Ancients rules. They used a figures scale of 1 to 20 and a ground scale of 1 inch to 20 paces.
This is the army list book to go with the rules.
This copy is in Poor condition. They have been well loved and used. Numerous marks (including an owners name inside) and wear but complete and useable. Of course, the book pictured is the one you will receive.
