Picked up a pair of extremely fine quality mop and bronze brush with a diameter of just over 1 inch. Allowing for some squeeze to do their job I would guess that they are possibly intended for 4 bore or more likely 6 bore barrels.

€25/$29US/£22/$37CAN/$37AUS) the pair plus postage from France. Ideal for your wall gun, small punt gun, large fowling piece or ball elephant gun!
