That appears to be a deluxe boxed Leech and Rigdon.
or is that a brass frame ?
High Standard also offered a Deluxe Boxed Griswald & Gunnison and Schneider & Glassick.
These came with nice wood box (like shown) and accessories, including a pistol flask, wrench in the Gray lined compartmented box.
There was also CS belt buckle.
The guns were also offered alone, sans Box & accessories or buckle at reduced retail.
