"Feel free to use this system to discuss your doubles, drillings, combination guns, other fine firearms, and related material. The rules are really simple: Stay on the subject matter, keep it clean, and contribute answers when you can!" Dave's preamble at the top of the forum.
"Other fine firearms" is expansive and doesn't limit discussion to doubleguns, and has been noted, already includes single-shot.
BB aka Ed, would you stand a little closer to the drain? I'd like to take a group photo. Move closer. Keep moving...I'll tell you when to stop.
