Lyman Sight for Thompson 1928A

grabcad

This is a step model of a Thompson 1928A Lyman sight created from WWII arsenal blueprints. This is one of my favorite parts of the Thompson, the detail and precision of these sights are really something to see. It is rendered with the sight in the up position, providing for yardage compensation for bullet drop; when folded down it's protected and a grove is set there for close quarters combat. Enjoy and let me know your thoughts...
