I have a rather nice 12 bore sle gun,from around 1926, with the Andrews Toledo steel bbls....but no makers name on it.
Abe Chaber cleaned the gun & locks, seemed the locks were made by Britte,by the mark he found under the main spring.
I've seen a good few rather nice Belgian guns with these bbls
I love mine,its got lovely burl wood, Purdey "Nose" 3rd fastener,
bushed pins & hinged trigger...I'd love to know who made it
I love nice Belgian Guns
cheers
